ukimsanov e6aa7feda9 fix(skill): hard landmine — search asset-descriptions.md before composing a logo
Verified root cause of the heygen + huly logo miss across the last two
real-AI-test runs:

  - SVG capture filenames are content-hash slugs (svg-<8char>.svg), so
    the brand name is NOT in the filename. The real heygen lockup is at
    svg-54ea56cd.svg; the real huly wordmark is at svg-ec034b11.svg.
  - In BOTH project captures, 0 / 32 (heygen) and 0 / 19 (huly) SVGs got
    the DOM-derived `isLogo: true` flag, so the `logo-<hash>.svg` prefix
    path from commit 5f290345 never fired. (Separate fix incoming for
    the detector itself.)
  - asset-descriptions.md CORRECTLY identifies both logos via Gemini
    Vision ("wordmark reading 'HeyGen' next to a four-lobed diamond" /
    "white wordmark... featuring a stylized 'H' icon to the left of the
    lowercase letters 'huly'") — agents just didn't search it before
    composing a fake.

The first run agent self-critique on both projects: "I had the workers
compose the [brand] mark from scratch... instead of dropping in the
actual captured logo... that was the wrong tradeoff for brand fidelity."

Doc changes (no code in this commit — code fixes for isLogo detection
+ no-Gemini fallback come in separate commits):

1. beat-builder-guide.md — new section "Logo discovery — search
   asset-descriptions.md BEFORE composing one" as a hard rule. Walks the
   agent through the 3-step procedure (grep brand name → open SVG to
   verify → reference from beat). Calls out the brand-fidelity violation
   explicitly: composing a logo when a captured one exists ships as
   off-brand. Notes the valid path of RECOLORING captured monochrome SVGs
   (which the heygen agent's later swap-in pass did correctly with the
   aurora gradient).

2. beat-builder-guide.md — new section "Captured videos — they're in
   the manifest, not on disk" documenting that capture/extracted/video-
   manifest.json carries every <video>'s URL + preview PNG, but the
   actual mp4s are not downloaded (intentional — sites with dozens of
   feature videos would blow up capture size). Includes the on-demand
   curl pattern for fetching just the one video the beat needs (e.g.
   heygen.com's "Orb" hero video = video-0 in the manifest, 768x768,
   "Turn your ideas into videos in minutes"). Don't bulk-download.

3. step-5-build.md — orchestrator's dispatch packet template updated:
   the placeholder `capture/assets/logo.svg — brand wordmark, white on
   transparent` was misleading because filenames are hashed, not
   `logo.svg`. Replaced with the realistic example
   `capture/assets/svg-54ea56cd.svg — wordmark "HeyGen" + four-lobed
   diamond icon (the real header logo)`, plus an explicit instruction:
   if the beat needs a logo and no captured SVG is resolved in the
   packet, the worker WILL compose a fake one. Resolve it explicitly
   in the dispatch, not as a "see asset-descriptions.md" pointer.

Net: zero code change. The capture pipeline already produces everything
agents need (descriptions in asset-descriptions.md, hash-named SVGs on
disk, video manifest with URLs). The miss was a doc-level discoverability
gap — agents didn't know to search the descriptions file or that videos
exist in a manifest. These landmines close that gap.

Followup commits (separate):
- Broaden isLogo DOM detection so `logo-<hash>.svg` prefix actually fires
  on real header/nav logos.
- Strengthen the no-Gemini fallback so asset-descriptions.md is still
  useful for teams without a Gemini API key.

ukimsanov cd5f6bcc7e fix(skill): SFX default volume = natural; preserve timing-alignment knobs
User instruction: "tweak the sfx applying in the way so that it wouldn't
tweak anything for the volume....let them just be as they are...(but it
still need to account for when in the audio actual sound effect starts
and end in order to be able to align, even if colliding into other sfx
or smt...)"

Stance change:
- Volume default → natural catalog-normalized level (no data-volume
  attribute emitted, = 1.0). Catalog is loudness-normalized at the file
  level, so emitting clips bare lets them ring at the level the catalog
  committed to.
- Timing alignment knobs preserved + elevated: data-media-start (skip
  dead air at head, = `onsetSec` from `sfx add` analysis) is now the
  first-class control. data-start / data-duration / data-media-start
  together align the audible attack to the beat frame.
- Multiple SFX may overlap; SFX may stack on VO. The engine has no
  auto-ducking — that's by design now, not a hazard to defend against.
- The lone common exception is a "felt, not heard" ambient bed (~0.1
  volume) — deliberate texture, not a duck.
- Per-clip nudge (when measured LUFS shows real mismatch) is the only
  remaining reason to set data-volume — per-clip override, not per-project
  policy.

Files changed:

1. scripts/assemble-index.mjs SFX emit (lines 343-371):
   - Was: `const vol = cue.volume != null ? cue.volume : 0.35;`
     followed by unconditional `data-volume="${vol}"` emit.
   - Now: emit data-volume only when cue.volume is explicitly set; emit
     data-media-start when cue.media_start is set. Block comment above
     the loop documents the natural-level rationale + the timing-alignment
     stance.

2. skills/hyperframes/references/sound-effects.md:
   - "The audio contract" section: marked data-volume as Optional;
     reordered to put data-media-start before data-volume (timing knob
     first, level knob second).
   - "Volume hierarchy" → renamed "Volume — default is natural, no
     auto-duck." Table reframed as "reference nudge ranges (only if
     needed)" instead of defaults. SFX row now reads "0.7-1.0 (default =
     natural)."
   - "Reading the numbers correctly" item 3: updated to "default is to
     omit data-volume" instead of "the volume hierarchy is your baseline."
   - Worked examples: removed `data-volume="0.3"` from the basic embed
     example; the bed-only example explicitly calls out 0.12 as an
     exception that proves the natural-level rule.

3. skills/website-to-hyperframes/references/step-3-storyboard.md SFX
   assignment section (lines 286-301):
   - Dropped `volume 0.3` / `volume 0.5` from the example list.
   - "Volume under narration: keep SFX at 0.2-0.3 under VO" replaced
     with "Volume — default natural" + the trust-the-mix prose.
   - Added a line emphasizing that timing precision (`data-media-start`)
     matters more now that volume defaults to natural.

Sections deliberately kept:
- The "Combining sounds" rule about `data-volume` for stack-clipping
  control (genuine audio engineering, not a duck heuristic).
- The accent-the-downbeat data-volume nudge in the "Sequence" pattern
  (variation, not ducking).
- All onset/peak/tail/peak-time mechanics — these are the timing
  alignment knobs the user explicitly asked to preserve.

Backward-compatible behavior:
- Cues that explicitly set `volume` still get `data-volume` emitted.
- Existing project HTMLs render unchanged — the change affects only how
  new assemblies emit SFX.

ukimsanov f293d9daf3 feat(skill): preview-beat.mjs + _beat-skeleton.html for faster beat iteration
Two friction-reducers from the real-AI-test feedback list:

1. scripts/preview-beat.mjs (~100 LOC)
   - Snapshot ONLY the frames inside a single beat's window. Solves the
     "I built beat-3, I want to see only beat-3's frames" iteration loop
     without scanning past sibling beats in a full-timeline snapshot.
   - Walks compositions/ in the same sort order as w2h-prep's
     scanCompositionsDir (readdirSync.sort, skip captions.html), sums each
     beat's data-duration to compute the target's cumulative start_s,
     then invokes `hyperframes snapshot . --at <t1>,<t2>,...,<tN>` with
     frames evenly spaced inside [start_s, start_s+duration_s).
   - Beat arg accepts: a path under compositions/, a bare filename, OR
     the composition-id slug (case-insensitive). Whichever the agent has
     handy.
   - Required project state: index.html must exist (assembler ran at
     least once); otherwise dies with a clear "run assemble-index first"
     message.
   - Smoke-tested against synthetic 3-beat fixture: target by filename,
     target by id slug, missing-beat error, missing-index error — all
     four paths behave as expected.

2. templates/_beat-skeleton.html (~80 LOC)
   - File copy of the starter template from beat-builder-guide.md Step 2,
     so the agent can `cp` instead of paste-from-docs when starting a new
     beat. Faster, less chance of drift between docs and on-disk content.
   - Pre-wires the patterns each landmine defuses, with inline comments
     pointing to the landmine number in step-5-build.md. Specifically
     honors: #10 full-bleed bg child div (not root background:), the
     frame-0 black trap (inline style="opacity:1"), GSAP transform-only
     tween whitelist, the three-string match (root id / __timelines key /
     dispatch slug), no inline <script src=...> for GSAP / HyperShader
     (assembler emits both at root).
   - Lives under templates/ not compositions/ so w2h-prep's scanner
     doesn't pick it up as a beat in a real project.

beat-builder-guide.md:
   - Step 2 now points at the on-disk skeleton (alongside the existing
     paste-from-docs option).
   - Step 4 adds the per-beat-window preview command next to the full
     `snapshot` command, with the contract (assemble-index must have run)
     spelled out.

ukimsanov 0e853ff7d4 fix(skill): w2h-prep — honor STORYBOARD's **Narration start:** offset
step-3-storyboard.md (line 436) and step-4-vo.md (line 116) instruct the
agent to write `**Narration start:** <n>s [optional parens]` in
STORYBOARD.md Global Direction when narration begins after t=0 (e.g.
0.8s after a hero intro settles, or to align with a music intro).

w2h-prep was ignoring that line in two places:

1. The voice object emitted to group_spec.json hardcoded `start_s: 0`,
   so assemble-index always wrote the narration <audio> with
   data-start="0" — meaning the audio played from t=0 regardless of
   what the storyboard said.

2. splitTranscriptPerScene partitioned transcript words by comparing
   AUDIO-TIME timestamps (start=0 = first audio sample) against
   COMPOSITION-TIME scene windows (start_s = cumulative beat duration
   from t=0). The two axes only coincide when narration starts at 0.
   With any offset > 0, words land in the wrong scenes or get dropped
   when they fall outside the partition windows.

The lived consequence on agents using a music-intro pattern: captions
silently desynced by exactly the narration offset, and the narration
audio played at t=0 instead of t=offset (overlapping the music intro).

Fix:

* parseNarrationStart(projectDir) parses the storyboard line
  defensively: handles `0.8s`, `0.8`, `2`, parenthetical commentary
  after the value. Defaults to 0 on absent file / missing line /
  malformed value / negative.

* splitTranscriptPerScene gains a voiceStartS param (default 0 ->
  backward-compatible). Word timestamps are shifted by +voiceStartS
  BEFORE partition, converting audio-time -> composition-time so the
  partition window matches.

* main() calls parseNarrationStart once, passes it to the splitter,
  and uses it for both voice.start_s and voice.duration_s
  (totalDuration - narrationStart, floored at 0).

Verified the parser against 5 cases (decimal+s+parens, missing file,
missing line, integer, malformed) and the splitter against a 4-word /
2-scene fixture with offset=0.8 (correct comp-time alignment) and
offset=0 (bit-identical to prior behavior).

Downstream impact:
- assemble-index already reads voice.start_s / voice.duration_s and
  emits them as data-start / data-duration on the narration <audio> —
  no change needed there.
- captions.mjs reads scene-local word timestamps and adds back scene
  start_s — also no change needed, because the splitter now emits
  scene-local times relative to the shifted comp-time word stream.

ukimsanov 64ed41de25 fix(skill): BGM under-VO volume 0.8 → 0.5 (match background-music.md)
assemble-index.mjs's `BGM_VOLUME = hasAnyVoice ? "0.8" : "0.9"` set the
under-VO ducked volume to 0.8 — well outside the 0.4–0.6 band that
references/background-music.md documents as "background music under VO"
(line 26), and triple the ~0.45 value the same doc uses in its example
storyboard "Music direction:" snippet (line 90).

The lived consequence on the heygen TTS run was a BGM bed that materially
competed with narration. The user's recent loudnorm check confirmed VO
was being clipped by music in the 0.8-bed renders.

Fix: 0.5 (mid of 0.4–0.6, top of the "simplest hold-low" 0.4–0.5 band
from background-music.md:37). Pure-music value (0.9) untouched — it
already sits at the top of the 0.7–0.9 doc range, which is correct per
the "or it disappears into the encoder noise floor" guidance (line 31).

Added a block comment above the constant linking back to the doc so
future readers don't re-derive (or re-break) the band.

Agents wanting per-section ducking should still use the documented
pattern-2 approach (embed same music id twice at different volumes);
this single-bed BGM emit is the floor, not the ceiling.

ukimsanov eb76972551 fix(skill): HyperShader host id must be bare sid, not el-<sid> prefix
assemble-index.mjs was emitting scene host divs with id="el-<sid>" in
all modes. HyperShader resolves scenes via document.getElementById(sid)
(packages/shader-transitions/src/hyper-shader.ts:289, 825) where sid is
the value from data-composition-id, and additionally requires the same
element to carry class="scene" (line 828 raises "scene ids not found in
DOM" otherwise).

With the el- prefix, init() consistently threw and no shader transitions
ran. The pattern only appeared after we added the el- prefix in a prior
fix for host-id uniqueness (across two compositions).

Fix: branch on useHyperShader. Shader mode uses the bare sid (lets
getElementById find it). Non-shader mode keeps el-<sid> (no
getElementById lookup happens there; the el- prefix preserves uniqueness
when an inner composition's root carries the same data-composition-id).

Verified against hyper-shader.ts source — both lookups (line 289 in the
seam compositor + line 825 in init's id-resolution check) are bare-id.
The class="scene" attribute was already conditional on useHyperShader so
no additional change needed.

No behavior change for non-shader compositions; restores shader transitions
for shader-mode compositions.

ukimsanov 41916db9e3 fix(producer): shim CJS __dirname/__filename in ESM banner
The producer bundle is emitted as ESM. The existing banner already shimmed
`require` via createRequire so CJS dep `require("fs")` calls work, but it
did NOT shim the CommonJS `__dirname` / `__filename` globals.

A bundled CJS dep (the ffmpeg/Emscripten wasm glue) references bare
`__dirname` to locate the wasm side-file — e.g. `scriptDirectory = __dirname
+ "/"` — and crashed at render time with:

    ReferenceError: __dirname is not defined in ES module scope

This affects every render through producer (not just w2h), and only
manifests on first render of a fresh checkout where the producer hasn't
been rebuilt with the shim.

The fix reconstructs both globals from import.meta.url inside the esbuild
banner, alongside the existing `require` shim. No behavior change for code
that doesn't reference __dirname; correctly resolves the CJS contract for
code that does.

Verified by re-running a producer render after rebuild — completes through
ffmpeg without the ReferenceError.

ukimsanov 4dcc3a6270 fix(skill): 4 doc-only landmines from real-AI-test feedback (heygen + huly)
Real test agents flagged specific issues their session burned tokens
discovering. Adding lived-experience documentation so future agents
hit these as one-line warnings instead of debug cycles.

step-1-design.md (brand-primary order):
- WAS: "List 8-12 colors..." (no order guidance).
- NOW: "List the brand-primary HEX FIRST. w2h-prep parses DESIGN.md
  and picks the first non-white / non-black hex it finds as the
  brand-primary for tokens.css emission."
- Why: heygen agent had to reorder DESIGN.md so cyan came first;
  prep silently picked the wrong color because the docs didn't tell
  agents about the parser's behavior.

step-5-build.md landmine #10 (sub-comp root background doesn't paint):
- Heygen beat-6 CTA opened on a blank white frame because the root
  div had `background: #050507` CSS which doesn't paint at render
  time (Studio preview paints it; MP4 render doesn't — renderer
  composites against transparency).
- Fix documented: full-bleed child div with `position: absolute;
  inset: 0; background: <color>` paints reliably.
- BAD/GOOD code example showing the wrong vs right pattern.
- Lint can't catch this — known gap, prose-only safeguard.

step-5-build.md landmine #11 (AVIF disguised as .jpg):
- Capture names downloaded images by URL extension, but server may
  serve AVIF to browsers that accept it. AVIF saved with .jpg can
  break headless render (ffmpeg image pipeline may not support AVIF
  depending on build).
- Heygen worker burned a swap cycle discovering learning-development
  .jpg / marketing.jpg were AVIF.
- Workaround documented: `file capture/assets/X.jpg` to detect; use
  different captured asset OR `ffmpeg -i broken.jpg good.png`.

step-5-build.md landmine #12 (SFX CLI gotchas — 4 huly hit):
- CWD drift breaks `source .env` — workaround: stay in project root,
  or use --env explicit path
- zsh doesn't word-split `$CLI sfx ...` — bash does, zsh doesn't.
  Either invoke CLI literally or use `${=CLI}` in zsh
- `sfx add <id>` requires prior `sfx search` (cache-populated, no
  fetch-by-id endpoint) — always search → add
- Some catalog clips are silent / -70 LUFS — `sfx add` prints LUFS
  in the analysis; if it shows ~-70 LUFS, re-search and pick another
  ID

Net: 4 doc additions, zero code change, zero behavior change. All
4 are lived-experience warnings that move "agent discovers via
multi-step debug" → "agent reads one line and proceeds." Each
addressable in fewer than 30 lines of prose.

Followups (not in this commit — separate commits per the verify-
first principle):
- BGM volume hardcode mismatch (assemble-index.mjs:190) — code fix
- voice.start_s hardcode (w2h-prep.mjs:533) — code fix
- Per-beat preview script — new file
- Beat-skeleton boilerplate — new file

ukimsanov 5a6caac18d fix(skill): end-to-end consistency audit — fix stale 'Step 5 fetches music' refs
After the music-fetch-moved-to-Step-3 change (commit 0a60427f), several
prose sections still referenced 'Step 5 fetches music' which is now
stale. Audit caught 4 leftover instances:

1. step-2-brief.md Q5 prose — top sentence said "decided here, then
   recorded ... so Step 5 can fetch it." Updated to "fetched in Step 3
   (Music Fetch sub-step) before beats are timed." With-music branch
   now describes the full Step 3 flow (search → add → read sparkline
   → record in Global Direction → Step 5 just embeds, no re-fetch).
   Without-music branch updated to mention "no music fetch happens"
   instead of "Step 5 skips the music fetch."

2. step-4-vo.md opening prose line — said "Music is deferred — see
   [Music](#music-deferred) at the bottom" with a DEAD anchor link
   (the section is now `## Music`, not `## Music (deferred)`).
   Replaced with "Music was decided in Step 2 (Q5) and fetched in
   Step 3's Music Fetch sub-step — already on disk by the time you
   reach Step 4 (see the [Music section](#music) below..."

3. background-music.md "Without that line, no music is added in
   Step 5" — updated to "no music is fetched in Step 3 and no BGM
   lane is added in Step 5."

4. background-music.md "If the key isn't set when Step 5 runs
   `hyperframes music`" — updated to "Step 3 runs `hyperframes
   music`."

Also re-verified end-to-end:
- No leftover "Brand Accents Pass" / "Composition + Accents" old
  section names anywhere.
- No leftover "Content-carrying / GPU effects (powerful, optional,
  rare)" priority-implying labels.
- visual-vocabulary.md shader references are NEUTRAL (one of four
  Transitions axis values + "1-2 shader moments is the ceiling"
  technical fact) — consistent with step-3's new shader framing.
- All anchor links resolve to existing sections.
- SKILL.md top-level prose has no stale references.
- background-music.md and step-4-vo.md no longer contradict on
  music timing.

Net: after this commit, the music flow is consistent across
step-2 → step-3 → step-4 → step-5 → background-music.md, and no
stale "deferred" / "Step 5 fetches" prose remains.

ukimsanov b4fe17ca74 fix(skill): truly neutralize technique inventory + shader prose
User catch: previous edits swung from positive-bias toward shaders
to negative-bias against them. Both are bias — equal-weight means
neutral. Per-beat agent choice, no implied ranking.

Renamed 4 technique categories to neutral descriptive labels:
- "Content-carrying (brand-true)" → "Uses captured brand assets"
- "Composed motion + typography" → "Built from primitives (CSS /
  SVG / Canvas / GSAP)"
- "Audio-driven (when music or VO is present)" → "Audio-paired
  (uses VO or music track as input)"
- "GPU effects (powerful, optional, rare)" → "Has GPU init cost"

Each label describes what the technique IS, not whether to prefer it.
Alphabetized within each category to remove implicit ordering.

Structural fix: moved "CSS scene transitions (30+ named patterns)"
from GPU-effects category to "Built from primitives" — CSS is not
GPU.

Removed all priority-implying shader language:
- "Shader transitions are optional and rare" → "Shader transition
  naming" (just describes block→runtime name pattern)
- "Most videos ship without any shader transitions" → DELETED
- "Reach for a shader transition only when a beat boundary is a
  true 'wow' moment" → DELETED
- "Most videos skip this section entirely" → "Skip this section
  when the video uses none"
- "Zero is fine and common" (transition matrix) → DELETED
- "(CSS crossfade) the default" → DELETED (positive bias toward CSS
  is the mirror image of the shader bias we just removed)
- "Most videos use only CSS crossfades + hard cuts and ship
  beautifully" → DELETED
- Opener punch list parenthetical "(Shader bloom is also valid here
  but optional; the non-shader openers above are equally punchy and
  cheaper)" → DELETED. Shader bloom now listed inline with other
  openers without disclaimers.

Technical constraints KEPT as facts (not preferences):
- "Cap: 1-2 shader transitions per video (more than 2 dilutes impact
  + adds GPU init time)"
- "CSS-only, no GPU init" / "WebGL — has GPU init cost"

Net: ~19 techniques across 4 neutral descriptive categories. No
technique framed as primary or rare. Shaders have a stated technical
cap but are equal-weight options alongside everything else. Decision
is per-beat, by the agent, based on the beat's concept.

ukimsanov 853385e578 fix(skill): expand step-3 technique inventory — full HyperFrames toolkit, not just 10 items
User caught: my de-shader edit listed 10 techniques but the parent
techniques.md has 13 + capabilities.md has more registry/Three.js
options. Agent reading my list might think "okay only these 10" and
still default to shaders for anything not on it. Need a more complete
inventory so agent has real variety to pick from.

Restructured the technique list into 4 categories (equal-weight, no
preferred default):

1. **Content-carrying (brand-true)** — 5 entries:
   - SVG path drawing (logo stroke-by-stroke)
   - HTML-in-Canvas with drawElementImage (named the actual VFX blocks:
     vfx-iphone-device, vfx-liquid-glass, vfx-shatter, vfx-portal,
     vfx-magnetic — agents didn't know these existed as one-add-away)
   - Video compositing (REAL captured <video> clips — w2h-specific
     value; capture downloads <video src> sources to assets/)
   - Lottie animation (captured .lottie/.json overlays)
   - Three.js custom scenes (full 3D when VFX blocks aren't enough)

2. **Composed motion + typography** — 9 entries:
   - Per-word kinetic typography (links to text-effects.md catalog
     of 24 named effects)
   - Variable font axis animation
   - Character-by-character typing
   - Counter animations
   - CSS 3D transforms
   - Clip-path reveal masks
   - Camera moves (push, dolly, parallax, orbit, rack focus, and
     leading-line-camera-traversal — cross-references the named
     motion pattern in this same step)
   - GSAP MotionPathPlugin (curves through space — cross-references
     the bezier-motion-path motion pattern)
   - Velocity-matched transitions (cross-references whip-pan +
     match-cut-handoff motion patterns)
   - Drifters (looping background elements for continuous depth)

3. **Audio-driven** — 1 entry:
   - Audio-reactive animation (bass/mid/treble → scale/glow/shape)
     with explicit "highest payoff in music-led / no-VO videos"

4. **GPU effects (powerful, optional, rare)** — 3 entries:
   - Shader transitions (kept the "max 1-2; zero is fine and common"
     framing from the previous commit)
   - WebGL Fragment Shader Art (full GPU generative backgrounds)
   - 30+ CSS scene transitions (the lighter-than-shaders option many
     agents missed — push, scale, dissolve, blur, 3D flip, etc.)

Net effect: agent reading step-3 now sees ~18 named techniques across
4 categories (vs the previous 10-item flat list). Shaders are now 1
of 18, in the "rare/optional" category at the END. The "agent defaults
to shaders for hero moments" pattern should be replaced with "agent
picks from the toolkit — SVG draw, HTML-in-Canvas mockup, real
captured video, Lottie, kinetic type, camera move, etc.".

Also added explicit cross-references between the technique inventory
and the "Named motion patterns" section (leading-line-camera-traversal,
match-cut-handoff, whip-pan, bezier-motion-path) so agents see them
as related primitives, not separate doc layers.

ukimsanov 7439a34238 fix(skill): de-bias step-3 away from defaulting to shader transitions
User observed: every test project uses shaders. Looked at the prose
and found 7 spots in step-3 that subtly nudge agents toward shaders.
The parent skill's techniques.md catalog already lists shaders LAST
(#13 of 13) — the bias was concentrated in our w2h step-3.

Four edits (one per bias source, ordered by impact):

1. Global guardrails technique list — reordered to lead with brand-
   content-carrying techniques (SVG path drawing, HTML-in-Canvas,
   per-word kinetic typography, camera moves, CSS 3D, variable font,
   character typing, counter animations, canvas procedural,
   clip-path masks). Shaders moved to end with explicit "optional"
   + "most videos ship without them" framing.

2. Required Capabilities Discovery — removed the shader-specific
   bash grep that led the command list. Replaced with a generic
   `ls registry/blocks/` that surfaces everything (VFX blocks AND
   shaders) without privileging shaders by ordering. Added
   "Most videos ship without any registry-installed blocks at all;
   the core techniques carry the majority of beats."

3. Shader transitions framing — kept the canonical declaration
   format section but now explicitly says "Most videos ship without
   any shader transitions — CSS crossfades and hard cuts cover
   90%+ of inter-beat transitions cleanly. Reach for a shader
   transition only when a beat boundary is a true 'wow' moment."
   Section heading suffixed with "(only if you actually use shader
   transitions)" + "Most videos skip this section entirely."

4. Transition decision matrix — reordered columns:
   WAS:  Shader | CSS crossfade | Hard cut
   NOW:  CSS crossfade (default) | Hard cut | Shader (rare — opt-in)
   Shader column body explicit: "Max 1-2 per video; zero is fine
   and common. More than 2 flattens their impact + raises GPU init
   risk." (Previously: "1-2 shader transitions per video (hero +
   CTA)" which IMPLIED every video has 1-2.)

5. Opener punch list — reordered:
   WAS:  "a flash, a shader bloom, a logo strike, a kinetic word
         build, a particle burst"
   NOW:  "a logo strike, a kinetic word build, a particle burst, a
         captured hero illustration push-in, a 3D-rotating product
         photo, a typed-on terminal line, an SVG path drawing itself
         — (Shader bloom is also valid here but optional; the
         non-shader openers above are equally punchy and cheaper.)"

Net effect: agents reading step-3 see shaders as a powerful but
optional rare-use tool, not the default opener / transition / hero
treatment. The "every project uses shaders" pattern should drop.
Parent skill capabilities.md unchanged (it's reference, not authoring
guide — agents read for what shaders DO, not whether to use them).

ukimsanov 409a451d56 refactor(skill): three honest simplifications from reflective audit
User asked me to audit the WHOLE workflow with 'keep it simple till
max output quality' lens — find genuine cuts, not perform thoroughness.
Looked hard. Most of the skill is approximately right-sized (each
subsection prevents a specific failure mode). Three small cuts only:

1. step-4-vo.md Music section: ~17 lines → 1 sentence.
   Was a 4-paragraph "do NOT re-fetch or re-ask here" restatement.
   Music is decided + fetched in Step 3 already; this section is just
   a pointer. Now reads: "Already fetched in Step 3 Music Fetch...
   Step 4 may optionally align VO start to the track's quiet intro
   (note in `**Narration start:**`) — that's all."

2. step-2-brief.md "Let me see options" subsection: moved from mid-
   step (line 153, between "Mixed direction" and "Gate") to a
   collapsible-style section at the very end of the file. The
   in-flow version was a 1-line pointer; the full 3-option block
   lives at the bottom under "When the user says 'let me see options'".
   Most users have direction and skip past it — putting it at the
   end lowers cognitive load for the common path while keeping it
   accessible when needed. No content lost.

3. Killed todos: PHASE A (port plv2 check-compositions/validate
   scripts) and M8 (re-audit PR #1026 prose). Both were based on
   outdated assumptions:
   - PHASE A: main's w2h-verify.mjs (in our tree via merge) already
     covers the gap. No need to port plv2's scripts.
   - M8: we made implicit choices during the conflict resolution
     (kept brand-floor REQUIRED, kept ours on w2h skill files,
     etc.). Re-litigating those is churn for marginal benefit.
   Removing them from the todo list cleans the signal of what's
   actually pending.

Honest meta-note: my session pattern was "add features → user pushes
back → I justify." Cleaner pattern going forward: filter each
addition through "what specific failure does this prevent" BEFORE
proposing. If I can't answer that crisply, don't add it.
2026-06-11 18:01:49 -07:00
ukimsanov 5339f12e60 fix(skill): 5 minimal clarity edits from reflective audit
User flagged: I add features without always checking that each one
lands in the right step. Did a reflective audit of 7 potential gaps,
addressed 5 with minimal prose (~15 lines total), skipped 2 as
unnecessary (no-result search retry, music swap workflow — agents
handle these via standard CLI iteration; no special prose helps).

Each addition answers "why does this make output quality better?":

1. step-3 Music Fetch — "When music drives (no VO)" paragraph:
   The sparkline ▁▂▅█▇▃▁ maps to beat structure directly when music
   is the spine. ▁ → beats start; █ → reveals anchor; ▇▃ → cool-downs
   hold. Without this, agents handling music-led/visual-only videos
   defaulted to VO-style structuring. Unlocks Step 2 Q4 "no narration,
   visual-only" + Q5 "yes music" case.

2. step-4 voice section — explicit "agent picks voice ID from brief":
   WAS: "regenerate with a different voice if wrong" (implied agent
   picks). NOW: explicit "Match storyboard's VO direction line to the
   provider's voice catalog. Don't ask the user to pick a voice ID
   — the brief already locked the register." Removes a user
   question that adds friction without value (deterministic agent).

3. step-4 caption skin override:
   The captions.mjs `--skin <name>` flag exists but the skill didn't
   tell agents they could override the auto-pick. Added one line
   noting two production-ready skins (caption-pill-karaoke default,
   caption-highlight for bold/social) and when to force the override.
   Auto-pick (via inference.json scoring) is correct 99% of the time;
   override only when storyboard's tonal direction is explicitly
   loud/social/TikTok.

4. step-0 asset shortlist clarification:
   The "5-10 promising assets" list was confusing — user asked if
   it's a restriction on Step 3. Clarified: shortlist is a
   "deeper-inspection list," not a restriction. Step 3 picks per
   beat from the FULL pool. Prevents agent from limiting themselves
   to only the shortlisted assets when a non-shortlisted asset fits
   a specific beat better.

5. step-3 Asset discovery — "empty Gemini caption ≠ broken asset":
   Sharp can fail to rasterize exotic SVGs (external fonts,
   foreignObject, filters) that Chrome still renders fine at video
   time. Without this clarification, agents might skip a usable
   asset because its caption is empty. Tells them to fall back to
   contact-sheet thumbnail (Chrome-rendered, never hallucinated).

Deferred as unnecessary:
- No-result music search → agent handles via standard "retry with
  broader query" CLI behavior.
- Music swap workflow → agent edits `**Music file:**` line + re-runs
  prep; standard iteration, no special prose helps.

Applied user's meta-principle throughout: "ask if this is necessary;
keep it simple till the point where we get max output quality."

ukimsanov 0a60427fdf fix(skill): move music fetch from Step 5 to Step 3 (beats align to track structure)
User flag: music selection in Step 5 was the wrong timing. Music has
structural moments (builds, peaks, drops, fills) that the video's
rhythm should honor — a build at 22s wants beat N to land at 22s.
With Step-5 fetch, the storyboard wrote beat timing BLIND to the
actual track, then Step 5 produced a structural mismatch.

SFX timing was already correct (per-beat punctuation, decided in
storyboard, fetched in build with full beat context). Only music
needed the move.

New flow:
  Step 2 (yes/no/auto) → Step 3 Music Fetch (search + pick + add +
  inspect + record sparkline+peaks in STORYBOARD.md) → Step 3
  beat-timing AWARE of track structure → Step 4 (no-op for music)
  → Step 5 (just wire the already-on-disk file)

Changes:

step-3-storyboard.md:
- New ## Music Fetch section between PACING and Technique-pick.
  6 sub-steps: describe mood → search catalog → pick (collaborative
  or auto by score) → music add (downloads + prints LUFS/peaks/
  sparkline) → record in Global Direction → time beats against
  structure (build@22s → schedule reveal at 22s, etc.).
- Global Direction template adds:
    **Music file:** assets/music/<id>.<ext>
    **Music direction:** mood + volume rule
    **Music structure:** sparkline + peak + duration + suggested trim
- Updated the existing "Music direction details" subsection to
  reference Step 2 Q5 + background-music.md (renamed from
  "Underscore/music direction").

step-4-vo.md:
- Replaced "Music (storyboard-driven, decided in Step 2)" section
  with "Music (already fetched in Step 3 — verify timing only)".
  Explicitly: do NOT re-fetch or re-ask here. Step 4 may align VO
  start to music's quiet intro if relevant.

step-5-build.md:
- Background music paragraph: "track is already on disk from Step 3
  Music Fetch; do NOT re-fetch or re-search here. Just wire as a
  BGM <audio> on track lane 11 with data-volume per storyboard."

w2h-prep.mjs:
- New BGM detection block (after voice auto-detect). Parses
  STORYBOARD.md for `**Music file:** <path>` line; falls back to
  auto-detect from `assets/music/` (single-file or alphabetical with
  warning when >1). Emits `bgm_path` field in group_spec.json,
  which assemble-index.mjs already consumes (line 289).
- Smoke-verified end-to-end: storyboard with Music file line →
  bgm_path: "assets/music/<id>.mp3" in group_spec.

This closes the loop that was missing: music decision → fetch →
analysis → beat timing → group_spec → assembler → final video.

ukimsanov 547b855e77 fix(skill): make music flow explicit across step-2 → step-3 → step-4 → step-5
User flag: SFX flow is automatic (storyboard names cues, Step 5
fetches), but the music flow had a STALE contradiction — step-4
still said "music is deferred, w2h does not generate or fetch music,
do not ask the user about music" while step-5 + background-music.md
shipped full `hyperframes music` catalog flow in PHASE 0b. The user's
question 'is it automatic or at least asked' surfaced the gap.

Net: music is now a Step-2 user-preference question with the same
collaborative/auto-decide pattern as TTS provider and captions.

step-2-brief.md:
- Added Question 5: "Background music?" with three options (yes /
  no / auto-decide). Notes 💬 user-preference + auto-decide rule
  (brand reel→yes; product demo→no; ambiguous→no).
- Renumbered "Format" from Q5 → Q6.
- Explicit pipeline wiring: decision flows to Step 3's Global
  Direction Music line, Step 5 fetches via `hyperframes music
  search`/`add`.

step-3-storyboard.md:
- Global Direction template now includes a `**Music direction:**`
  line (only populated if Step 2 Q5 said yes) — one line of mood
  for `hyperframes music search` + volume rule.
- "Underscore/music direction" subsection renamed to "Music
  direction details" and references Step 2 Q5 + background-music.md.

step-4-vo.md:
- Replaced "Music (deferred) ... do not ask the user about music
  at this step; if they want it, they'll tell you" with "Music
  (storyboard-driven, decided in Step 2)". Explicitly says do NOT
  re-ask here; the brief locked the decision. Points at Step 5
  fetch via `hyperframes music search`/`add` and at background-
  music.md for the model.

Net flow:
  Step 2 (asks user) → Step 3 (records in Global Direction)
  → Step 4 (skipped, no re-ask) → Step 5 (fetches via CLI)

ukimsanov 229a2f396c fix(skill): tighten contact-sheet inspection rigor in step-3 + beat-builder
User flag: skill needs to push agents toward cell-by-cell inspection
of every contact sheet (assets, SVGs, screenshots, render snapshots) —
not a quick browse. Step 0 and Step 6 already enforce this rigor;
Step 3 and the beat-builder sub-agent's Step 4 (snapshot review) did
not.

Step-3-storyboard.md (Asset discovery section):
- WAS: "View `capture/assets/contact-sheet-*.jpg` and `capture/
  assets/svgs/contact-sheet-*.jpg`. This is how you browse..."
  (2 of 3 contact-sheet types listed; "browse" not "every cell").
- NOW: bulleted list of ALL THREE contact-sheet types:
  • capture/screenshots/contact-sheet-*.jpg (page-scroll screenshots)
  • capture/assets/contact-sheet-*.jpg (raster images)
  • capture/assets/svgs/contact-sheet-*.jpg (SVGs as thumbnails —
    filenames are content-hash; the thumbnail IS the source of truth)
  Plus: "re-view ... every cell, no skimming. Step 0 had you do the
  initial cell-by-cell view; here in Step 3 you re-open each sheet to
  assign specific cells to specific beats. Open the cell, name what
  you see, then decide. Do not assign assets from memory."

Beat-builder-guide.md (Step 4 sub-agent snapshot review):
- WAS: "READ the contact sheet. For each frame: [checklist]."
- NOW: "VIEW the contact sheet cell-by-cell. Not a glance — look at
  EVERY frame your snapshot produced, in order. For each frame, write
  one short sentence naming what you see..."

Net: all four contact-sheet review surfaces (Step 0 / Step 3 / Step 5
sub-agent snapshot review / Step 6 final snapshot review) now use the
same "every cell, name what you see, no skimming" language.

ukimsanov 8e1ecc36b4 fix(capture): drop unused err param in SVG rasterize catch block
oxlint flagged `catch (err)` after the SVG→PNG sharp fix. The catch
intentionally swallows (sharp can fail on exotic SVG features and the
contact sheet remains the authoritative fallback). Switch to bare
`catch {}` since the error object isn't referenced.

Follow-up to 5f290345.
2026-06-11 16:35:11 -07:00
ukimsanov 5f290345d1 fix(capture): content-hash SVG slugs + render SVG→PNG for Gemini captions
Two distinct bugs in the capture pipeline surfaced when AI agents
ran on heygen.com and huly.io captures. Verified visually against
real captured SVGs before fixing.

BUG 1 — SVG slug scramble (assetDownloader.ts):

Label-derived slugging in the downloaded-image flow assigned the wrong
filename to several captured SVGs. Verified by rasterizing the actual
bytes via sharp:
  heygen-logo.svg → contains the GOOGLE wordmark
  hubspot-logo.svg → contains the TRIVAGO logo
  logo.svg → contains the real HeyGen wordmark (correct)
  workday.svg → contains workday (correct)

Root cause: catalog → URL alignment drift in label inference (aria-label
/ nearest-heading / sectionClasses propagating across partner-logo
carousels). Hard to reliably fix in the inference layer.

Fix: switch both SVG-naming flows (inline DOM extraction + downloaded
URLs) to content-addressable filenames. Slug becomes
`svg-<8char-sha1>.svg` or `logo-<hash>.svg` when the DOM marks it as a
logo (the isLogo flag is more reliable than label inference). Filename
becomes a function of the bytes — can never mismatch the content.
Rasters keep human-readable catalog slugs; only SVGs change.

BUG 2 — Gemini hallucinating on SVG content (contentExtractor.ts):

Previous code sent raw SVG path markup as TEXT to gemini-3.1-flash-lite-
preview and asked it to interpret what the paths would render. Real
descriptions in asset-descriptions.md:
  hubspot-logo.svg → "stylized text 'VIVIENNE'" (pure hallucination)
  workday.svg → "text 'wrestling'" (pure hallucination)
  huly-logo.svg → "text 'Kube'" (pure hallucination)
  heygen-logo.svg → "text 'oogo'" (partial-misread of Google)

Fix: rasterize each SVG to a 256×256 PNG via sharp first, then send
the PNG bytes to the Vision API — same call shape we already use for
raster images. Vision models can actually see PNGs reliably.

Adds a polarity check: SVGs with white-glyph fills (e.g. huly-logo.svg
uses fill="#fff") flatten against dark slate; dark-glyph SVGs flatten
against white. Without polarity detection, white-on-white renders as a
blank PNG and Gemini sees nothing. Smoke-verified: huly's "✕ huly"
wordmark + Google wordmark + HeyGen wordmark + trivago logo all render
correctly against contrasting backgrounds.

Prompt updated to add: "If you see a wordmark, READ THE LETTERS
LITERALLY — do not guess a brand from context." Guards against the
remaining failure mode where Gemini sees the pixels correctly but
extrapolates a wrong brand from contextual cues.

Failure modes: sharp's SVG rasterizer can fail on exotic features
(external fonts, foreignObject, missing-primitive filters); those SVGs
fall back to no-caption rather than blocking the capture. The contact
sheet (Chrome-rendered) is still the agent's authoritative source for
SVG content.

ukimsanov 6bdd975ec5 fix(skill): step-2 brief options — rebalance the 3 sample creative directions
Audit caught one more leftover from the old "compose-default" philosophy:
the 3 sample options in step-2-brief.md were ALL composition-heavy, with
the closing line explicitly forbidding any option whose primary content
is "the screenshot of X."

Under the new "agent picks per beat" philosophy, the three sample
options should illustrate a MEANINGFUL SPECTRUM so the user sees a
real choice:

- Option A: composition-leaning (kept as-is — kinetic typography +
  composed kanban + drawn brand mark)
- Option B: layered (changed from "no screenshots, three composed
  panels" to "captured product assets layered with composed kinetic
  type and brand washes")
- Option C: asset-leaning (changed from "three composed UI scenes"
  to "real captured screenshots in a 3D MacBook mockup + captured
  AI-chat with typewriter sync + captured command palette")

Replaced the closing instruction:
- WAS: "Each option states... where (if anywhere) a captured asset
  shows up as an accent. Never an option whose primary content is
  'the screenshot of X' — if you find yourself writing one, flip
  it: name what gets composed, then where the brand accent lands
  on top."
- NOW: "Each option names: the arc, the dominant visual approach
  (composition-leaning / layered / asset-leaning), and a sample of
  what carries each beat. The three options should vary in approach
  so the user sees a meaningful spectrum — proposing three
  composition-heavy options or three asset-heavy options doesn't
  give the user a real choice. The agent picks per-beat technique
  downstream regardless of which option the user picks."

Final state: every conflicting "compose-default" / "assets-decorate" /
"never-screenshot" phrase across the entire skill has been removed.
Captured assets and composed visuals are at equal weight everywhere
in the prose; agent decides per beat.
2026-06-11 15:31:24 -07:00
ukimsanov a2524b4754 fix(skill): 4 leftover asset-philosophy contradictions from prior revision
Post-revision audit caught 4 places where prior "compose-default,
assets-decorate" language survived the b6050b13 rewrite and now
contradicts the new "agent picks per beat, no default" philosophy.

1. SKILL.md:102 — "do the brand-accents pass at the end" referenced
   the OLD section name (now "Asset & Brand Floor") AND framed assets
   as accents. Rewrote: "decide per beat what visual content carries
   it (captured / composed / both layered)... verify the Asset &
   Brand Floor at the end."

2. step-0-capture.md:110 — "potential brand accents... typically
   logo/hero/gradient/brand mark... Most won't make it into the
   final video." Two contradictions: (a) framed assets as
   accents, (b) "Most won't make it" implied a high skip rate
   that contradicts the new "use what serves the meaning" rule.
   Rewrote as: "3-7 visually distinctive candidates... Step 3
   decides per beat whether each captured asset, a composed visual,
   or both layered serves the beat best."

3. step-3-storyboard.md:83 — Asset discovery paragraph had two
   contradicting lines: "When you find an asset that earns its place
   as a brand accent" + "compose the UI from divs/CSS in your beats
   rather than pasting the screenshot" + "strongest captured assets
   for video accents are usually the brand logo, hero illustration,
   and gradient/texture backgrounds." All three reinforced the OLD
   accent/compose-default philosophy. Rewrote to: assets-as-relevant-
   to-beat framing + per-beat decision language + explicit "screenshot
   is fine when the beat's meaning is the product itself" carve-out
   (with the contact-sheet/scroll-screenshot no-use rule preserved).

4. step-3-storyboard.md (after Asset use table) — orphaned bullet
   "A beat with no obvious accent need stays accent-free. The
   composed visual is enough." Leftover from the OLD per-beat
   structure that I missed deleting in the b6050b13 rewrite.
   Deleted.

Acceptable "accent" uses left in place (CSS color/class context,
not asset philosophy): beat-builder-guide.md:149 ("brand bg/accent
hex" — CSS color), beat-builder-guide.md:250 (decorative-class
regex "...accent|tile|ghost|gradient..." — perception-gate class
pattern), step-0/1/3 color-palette references ("white backgrounds
with purple accent" etc.), capabilities.md shader-transition prose
("accent flash" etc.).

ukimsanov b6050b1327 refactor(skill): asset philosophy — agent picks per beat, no default direction, vary across reel
Per-session critique surfaced that our step-3 had a strong "compose by
default; assets decorate" bias that conflicted with the actual value
prop of website-to-hyperframes (we HAVE the brand's real assets;
leverage them). Main went the opposite direction with PR #1026
("captured assets are first-class primaries"). User picked a third
position that captures the nuance:

1. Both composed and captured are first-class — agent decides per beat
2. Beats usually CORRELATE both — pure composition or pure capture
   rarely produces the strongest beat
3. Variation across beats — different content-source proportions per
   beat, varied motion patterns, varied framing — keep ONE stylistic
   spine (the brand) but vary the technique
4. Multiplicity inside a beat isn't spam when the concept needs it
   (46-SVG partner-logo grid IS the concept, not spam)
5. Brand-mark floor (opener + closer + signature visual) unchanged

Net 5 edits in step-3-storyboard.md:

- Opening framing (line 3): captured assets and composed visuals
  are both first-class beat content; agent decides per beat.
- Global guardrails (line 132): removed "captured assets are
  accents... typically 2-4 across the whole video" cap. Replaced
  with "both load-bearing, most beats correlate both".
- "Compose the load-bearing visuals yourself" paragraph (line 308):
  flipped from "compose by default, accent with assets" to "pick
  per beat: composed / captured / layered, with examples of each
  including the 46-SVG grid use case". Added explicit "asset use
  isn't spamming when concept needs it" paragraph.
- "Composition + Accents" per-beat block (line 346): renamed to
  "Visual content + technique"; restructured to list three options
  at equal weight (composed / captured / both layered).
- "Brand Accents Pass" section (line 393): renamed to "Asset & Brand
  Floor (verify after beats are written)". Kept the floor (brand
  mark + signature visual) and added a variation check. Dropped the
  "2-4 accents total" cap. Dropped the "SKIP for product UI" default.
  Asset use table no longer lists SKIP rows — only assets actually
  used appear.

Result: no biasing language toward composition or capture; agent
trusted to make context-aware per-beat decisions; one stylistic
spine + technique variation principle stated explicitly.

ukimsanov 3a36f436d8 fix(skill): pre-real-AI-test audit — 4 contradictions/leftover refs
Final audit before live AI-agent test runs caught 4 issues that would
surface as 404s, confusion, or stale links during agent runs.

1. step-3-storyboard.md text-effects path was wrong:
   `text-effects/effects/[id].json` → `text-effects/specs/[id].json`.
   The `effects/` folder doesn't exist in our worktree; specs/ does
   (24 JSONs). Added a "Source lookup" note: bundled local copy at
   `skills/hyperframes/assets/text-effects/specs/<id>.json` (always
   present), upstream fallback at `.agents/skills/animate-text/
   assets/specs/` when /animate-text skill is loaded.

2. step-6-validate.md stale anchor:
   Was pointing at `step-5-build.md#5-gsap-script-tag-is-required-
   -no-sri`, but step-5's #5 is the drifter `repeat:-1` rule, NOT
   the GSAP script tag rule (that lives in landmine #1 — sub-comp
   contract — and self-check grep #7). Updated.

3. Beat-name placeholder inconsistency: normalized `beat-N-name`
   (6 occurrences in beat-builder-guide template + step-5 dispatch
   prompt) to `beat-N-<slug>` matching the rest of the codebase.
   `<slug>` is unambiguously a slot to fill; `name` could be read
   as literal.

4. text-effects bundle/external contradiction documented:
   text-effects.md (parent skill, from main) says "We do NOT ship
   the catalog." Our worktree DOES ship 24 specs (kept via merge;
   PR #1026 dropped them on main but our resolution took ours).
   step-3's new "Source lookup" note resolves this — bundled is
   always present, upstream is opt-in.

Net effect: agents reading step-3, step-5, step-6, or beat-builder
will find every referenced file/anchor on first lookup.

ukimsanov 8d7ea432a8 refactor(skill): normalize hook/motion/archetype taxonomies to equal weight + add 2 Bezier patterns
Self-critique caught: prior taxonomy additions had 6x variance in word
count + biasing language (superlatives, cross-pattern comparisons,
named reference implementations) that would cause agents to over-pick
the dense entries. Determinism requires uniform weight.

Hook patterns (table, 14 rows):
- Trimmed my 4 additions (contradiction-reveal, time-stamped-urgency,
  aftermath-open, negative-space) from multi-sentence cells to the
  same 1-sentence "when" + quoted example shape as the original 10.
- Closing prose: removed brand-voice / platform / message bias
  suggestions ("clinical fintech ≠ visceral metaphor", etc.).
- Added "every entry is a known scroll-stopper, none is 'better'
  than another" explicit note.

Motion patterns (list, 10 entries now):
- Rewrote all 8 prior entries to the same shape: mechanism + one
  concrete number/constraint. Word counts now 25-45 per entry
  (was 32-180+).
- Removed biasing language: "Best for X", "powerful when",
  "Edgar Wright cuts", "stillness IS the impact", "punchy".
- Removed the code block + named reference implementation from
  leading-line-camera-traversal. Mechanism stated in prose at the
  same depth as every other entry.
- Added intro note: "Every entry below is equal-weight — none is
  preferred or 'best'. Pick the one that matches the beat's intent,
  not the one that reads richest in this doc."

New patterns (2, at equal weight):
- `custom-cubic-bezier-ease` — register a CustomEase via cubic-bezier
  coords when standard GSAP eases don't carry the intended personality.
- `bezier-motion-path` — element follows a curve via GSAP MotionPath
  plugin reading an SVG <path d="..."/>.

Archetypes (5 entries):
- Trimmed BAB (was 75 words, longest) to 30-35 like the others.
- Removed cross-archetype comparisons ("shallower than PAS; proof-
  heavier than Future-Pacing") that created selection bias.
- Swapped "Best for X" framing to neutral "Applies when X".
- Added "Every entry below is equal-weight — none is preferred."

ukimsanov 9762dabb25 feat(skill): expand hook + motion taxonomies (post-PHASE-D additions)
Per session-17 follow-up: extending the named pattern libraries with
4 structurally-distinct hook patterns and 5 motion patterns. The new
motion pattern `leading-line-camera-traversal` documents the Vauban
prompt's camera-pan-across-large-canvas technique (verified against
fable-test/hyperframes-roadmap reference implementation).

New hook patterns (4):
- contradiction-reveal — attacks viewer's assumed knowledge head-on
- time-stamped-urgency — drops viewer into a scene already in motion
- aftermath-open — start resolved, rewind to show how (reverse chron)
- negative-space — first 1.0-1.5s intentionally empty (silence/black)

New motion patterns (5):
- leading-line-camera-traversal — viewport fixed, world canvas large
  (4000-12000px), GSAP tweens .world transform between named coords.
  Optional SVG leading-lines draw between camera moves. Reference impl:
  fable-test/hyperframes-roadmap/compositions/roadmap.html.
- match-cut-handoff — two adjacent beats share an element morphing
  in shape across the crossfade seam (logo → letter, circle → O).
- whip-pan — fast directional blur sweep between beats replacing the
  crossfade. Max twice per video. Orchestrator-wired via storyboard.
- earned-hold — dead-still 0.6-1.2s after rapid motion, music drops.
  Stillness IS the impact. Best before CTA in fast-paced reels.
- settling-overshoot — entering element overshoots 5-8px / 4-8% scale
  then jitters back at decreasing amplitude (2-3 dampened bounces).
  Two stacked GSAP tweens: back.out arrival + elastic.out follow-up.

ukimsanov b6fae4eab4 feat(skill): PHASE D — story craft (hook taxonomy + motion patterns + optional archetypes)
PHASE D1 universal extracts into step-3-storyboard.md:

- **Named hook patterns table (10 types)**: shocking-statistic /
  imagine / direct-address / pain-validation / visceral-metaphor /
  rhetorical-question / category-announcement / visual-spectacle /
  question-invitation / trend-positioning. Each with one-line "when
  to use" + a concrete VO example. Inserted after "Opener default"
  prose with explicit "don't combine more than one hook per opener"
  guardrail.

- **Three named motion patterns** in Per-Beat Direction so the
  storyboard names them and the worker implements (sourced from
  plv2 motion-language.md):
  - `stillness-before-climax` — 0.3-0.75s pause between major
    action and confirmation (narrative comma).
  - `exit-75-percent` — exit ≈ 75% of entry duration (not 50%,
    not 100%).
  - `multiplicative-breathing` — `scale = final * (1 + sin(t*freq)
    * amp)` driven by onUpdate, NOT yoyo. ±6px or ±2-5% minimum
    amplitude.

PHASE D2 optional archetypes as SECONDARY framing:

Inserted under "First decision: CONCEPT" as a clearly-optional
section. The Arc field (Problem→Solution / Reveal / Demonstration
/ Vibe / Comparison) stays as primary. Archetypes only apply when
the user's brief is launch-style or persuasion-heavy:

- PAS (Pain → Agitate → Solve)
- BAB (Before → After → Bridge)
- Future-Pacing
- Demo-Loop
- Feature-Benefit-Cascade

Each with one-line "when to use" + the typical opening shape.
Skipped plv2's persuasion-family framing (Pain/Authority/Social/
Cognitive/Hedonic) — wrong identity layer for w2h ("viral hook"
not "sales pitch" per Step -1).
2026-06-11 12:24:43 -07:00
ukimsanov cba37a1250 feat(skill): PHASE C — asset-existence gate + shader-transitions auto-derive
PHASE C as originally planned didn't apply — our w2h-prep.mjs evolved
past the plan's "280-LOC stub" baseline (now 476 → 603 LOC), and 4/6
"takes" from plv2's prep.mjs are already done. The remaining 2 are
preset-architecture-specific to plv2 (anchor-walk of section_plan.md,
asset-copy to public/) and don't fit our HTML-as-truth pipeline.

Instead, ship two small targeted improvements that genuinely fill gaps:

(a) Asset-existence pre-flight gate (~50 LOC):
  - Scans each beat HTML for `capture/assets/X` refs in src=/xlink:href=/
    CSS url() and verifies each resolves to a file on disk.
  - Emits `asset_check: { total_references, unique_assets, missing[] }`
    in group_spec.json so preflight-finalize and perception can flag it.
  - Prints a console warning per missing asset (with the beat ids that
    reference it). Catches "logo 404 at render time" BEFORE the user
    waits for a 30-second MP4 to bake.

(b) Shader-transitions auto-derive from STORYBOARD.md (~45 LOC):
  - Parses a canonical "## Shader Transitions" block:
    `- between <beat-id> and <beat-id>: shader=<name>[, duration=<n>]`
  - When ANY transition is declared, emits the full scenes/transitions
    chain with declared shaders on the declared boundaries and CSS
    crossfade (no `shader` field) on the rest. Invariant
    `scenes.length === transitions.length + 1` is honored.
  - When NO transitions are declared, the field is omitted — assembler
    falls through to vanilla GSAP, same backward-compatible default.
  - bg_color + accent_color derived from parsed DESIGN.md tokens.
  - Canonical format documented in step-3-storyboard.md under "Shader
    Transitions — block name ≠ shader name" so the agent knows the
    exact syntax.

Smoke-tested with a 2-beat synthetic project: missing asset surfaced
as expected; shader_transitions emitted with the right bg_color +
shader name + computed time/duration.

ukimsanov 46295b5635 feat(skill): PHASE B — absorb plv2 worker prompt rigor
PHASE B1: port universal video-grammar gems from plv2's hyperframes-scene.md
into beat-builder-guide.md. Skipped plv2-specific Tier-A bridge protocol,
design_chunks, and component-library selection (preset architecture, not
our identity).

beat-builder-guide.md additions:
- Pre-Write Cheat Sheet items 6 & 7: GSAP transform alias whitelist
  (only x/y/scale/scaleX/scaleY/rotation/opacity, never width/height/
  top/left) + CSS-baked transform vs GSAP transform mutual exclusion
- Known landmines #5/#6/#7: one-primary-at-a-time handoff rule, no
  literal HTML opening tags in comments, no per-beat exit tweens
- "Macro-camera scale headroom" section: maxScale = 0.88 * 1920 /
  r.width formula + measure-don't-derive offset recipe
- Rules block: 5 new rules (TRANSFORM PROPS, CSS+GSAP TRANSFORM,
  EXITS, ONE PRIMARY, COMMENTS) + TIMELINE rule strengthened to
  literal data-composition-id (not variable indirection)
- DONE-criterion self-check: 3 new grep gates (#9 tween-property
  whitelist, #10 literal HTML in comments, #11 literal timeline key)

PHASE B2: port plv2 hyperframes-finalize.md Step 3.5's 5-category
visual inspection protocol into step-6-validate.md, inserted between
the per-beat snapshot review and the critic sub-agent.

step-6-validate.md additions:
- "Mandatory Visual Inspection Checklist (per snapshot, 5 categories)"
  section: illegibility/out-of-bounds/competing-primaries/cramped/
  seam-jank. Each row maps to: what to look for, the machine signal
  that should have caught it, in-place fix direction
- Adopts plv2's "the eye is fragile" framing verbatim
- Re-application sanity rule for transform+height Edits

ukimsanov fefc799177 feat(music): parallel hyperframes music command + background-music.md
PHASE 0b/0c per PLAN.md — music gets its own command surface (Option A,
cleaner UX than `--type music` flag on sfx). Implementation reuses sfx's
auth + analyze modules verbatim, has its own state cache (writes to
assets/music/ not assets/sfx/), and passes type="music" to the same
searchSounds cloud endpoint that backs sfx.

New files:
- packages/cli/src/commands/music.ts (dispatcher, mirrors sfx.ts)
- packages/cli/src/commands/music/{search,add,inspect,state}.ts
- skills/website-to-hyperframes/references/background-music.md

Wired into:
- cli.ts (music subCommands entry)
- help.ts ("AI & Integrations" group)
- step-5-build.md (paragraph linking background-music.md)

Smoke-verified:
- music search "moody ambient pad" returns real catalog tracks (live API)
- music --help shows search/add/inspect
- music inspect resolves clips from assets/music/
- sfx tests still pass (12/12), CLI typecheck clean, full build green

Cherry-pick of 995dbb4f (originally on feat/sfx-audio-search) into
feat/w2h-restructure-v3, now mergeable because main was just folded
into this branch and brought cloud/auth.

CLI (packages/cli/src/commands/sfx/):
- list / search / add / inspect
- analyze.ts (ffmpeg ebur128 + silencedetect, LUFS/peak/onset/tail
  + loudness sparkline + suggested trim)
- auth.ts (free HeyGen key opt-in instead of raw 401)
- catalog-manifest.ts (180 clips across 22 families, generated)

Skill docs:
- skills/hyperframes/references/sound-effects.md (the global model)
- skills/hyperframes/SKILL.md + beat-direction.md link sound-effects.md
- skills/website-to-hyperframes step-3/step-5 migrate off bundled SFX
  onto catalog flow (incorporates session-13/16 prose: orchestrator
  authoring stays out, landmines stay in)
- assets/sfx/ deleted (20 mp3 + manifest.json + CREDITS.md)

Cherry-pick conflicts resolved manually:
- step-3-storyboard.md SFX section: took catalog version
- step-5-build.md: kept our session-13/16 structure (landmines,
  assembler-owned index.html), folded in commit's catalog-analysis

ukimsanov 390908b412 fix(cli): adapt session-17 tests to main's evolved lintProject API
Post-merge fixes after merging main into feat/w2h-restructure-v3:

- packages/cli/src/utils/lintProject.test.ts: lintProject() became
  async in main. Convert 10 it()-block sync arrows to async and add
  `await` to lintProject calls (preserves our 192 LOC of session
  test coverage for missing_local_asset variants).

- packages/cli/src/capture/assetNaming.test.ts: delete. The test
  referenced session-only CatalogedAsset fields (slotRole, bbox,
  altText, enclosingHref) that main's type doesn't have. We took
  main's assetCataloger, so the test is testing functionality we
  no longer ship.

ukimsanov 3e26740625 chore: merge main into feat/w2h-restructure-v3
Pull 463 commits of upstream evolution into our session-17 work.
Required because feat/sfx-audio-search depends on cloud/auth modules
that landed in main after our 2026-05-20 fork point.

Conflict resolution (29 files, hybrid approach):
- bun.lock + packages/cli/package.json — main (dep churn)
- packages/cli/src/capture/* (5 files) — main (active CLI maintenance)
- packages/cli/src/commands/snapshot.ts — main
- packages/core/src/lint/rules/{fonts,fonts.test,composition.test}.ts —
  main (alias system + new rules we lacked, our rule already there)
- skills/hyperframes/* (9 files) — main (parent skill is main's domain)
- skills/website-to-hyperframes/* (11 files) — ours (preserves session
  13-16 work: landmines, dispatch packet, assembler, scripts)

Followup needed: audit main's 16 w2h-skill commits since fork and
port specific improvements (w2h-verify script, primitive-toolkit
framing, brand-defaults rename, captured-assets-as-primaries shift,
SKILL.md pointer-index slim, etc).

  preflight-finalize, verify-output, check-rendered-perception,
  w2h-dispatch-packet)
- skill reference reorg (steps 0-6, beat-builder-guide,
  capabilities, SKILL.md)
- capture/lint infra updates (assetCataloger, assetDownloader,
  tokenExtractor, lintProject, fonts rule)
- PLAN.md (the steal+adapt plan for sessions 17+)

Commit exists to provide a rollback point before merging 463
commits of upstream main into this branch. Will likely be
squashed/restructured before any PR.

James RussoandClaude Fable 5 30fcede44e refactor(cli): restore exact-match Cursor rule (revert unsourced loosening) (#1334)
Follow-up to #1328. That PR loosened the Cursor TERM_PROGRAM check from exact
`=== "cursor"` to `?.toLowerCase() === "cursor"` "for parity with Windsurf" —
but the parity is false. Windsurf is matched case-insensitively because its
sources genuinely disagree on casing ("windsurf" vs "Windsurf"); Cursor
consistently emits lowercase "cursor", so nothing justified loosening an
existing, working, exact-match rule. Per review feedback on #1328
(Magi/Hermes), revert Cursor to exact match and drop the TERM_PROGRAM=Cursor
test. Windsurf stays case-insensitive (sourced); its comment now documents the
asymmetry as intentional.

No functional change — Cursor always emitted lowercase, so detection is
unchanged; this just removes an unsourced false-positive surface.

James RussoandClaude Fable 5 e0ecd4d2d1 feat(cli): detect Windsurf, Cline, Gemini CLI, and Crush agents (#1328)
Rebased onto main after #1294 merged. Adds four coding-agent vendors to
detectAgentRuntime() (existence-only checks, source/runtime-verified):
- windsurf — TERM_PROGRAM=windsurf (case-insensitive)
- cline — CLINE_ACTIVE (default vscode-terminal path)
- gemini_cli — GEMINI_CLI (runtime-confirmed; distinct from the managed-agent
  /.agents/ detector, which runs ahead of VENDOR_RULES and wins when both match)
- crush — CRUSH (runtime-confirmed)

Also makes the cursor rule case-insensitive for parity with windsurf, and adds
a code-resident "deliberately NOT added" section (OpenHands/Aider/Goose/
opencode/Roo/Amp/Devin/Jules/Factory) carrying the empirical rejection
rationale.

Test isolation: the Gemini managed-agent suite now clears its node:os/node:fs
doMock registrations in afterEach so they don't leak into the env-var-only
suites that follow it in the same file.

James RussoandClaude Fable 5 0766eb8144 feat(cli): detect Gemini managed-agent sandbox in detectAgentRuntime (#1294)
* feat(cli): detect Gemini managed-agent sandbox in detectAgentRuntime

Add `gemini_managed_agent` to the AgentRuntime union and a dedicated
isGeminiManagedAgent() detector. Empirical signal pair (from live-sandbox
introspection by gemini-agent, env_id b9db4e56, 2026-06-09):

  existsSync('/.agents/AGENTS.md')  AND  isGVisor()

The conjunction is what makes the rule safe:

  - `/.agents/AGENTS.md` excludes generic gVisor surfaces (GKE Sandbox,
    Cloud Run gen2) that don't mount the managed-agent layout.
  - The gVisor kernel check excludes a dev box that happens to have a
    stray `/.agents/` directory.

Implementation notes:

  - Filesystem-based check runs ahead of the env-var-only VENDOR_RULES
    loop. VENDOR_RULES is documented as "Only checks for the EXISTENCE
    of well-known env vars — never reads their values"; the Gemini
    signal is filesystem + kernel, not env, so it gets a dedicated
    branch rather than shoehorning into the rule list.

  - GEMINI_API_KEY is deliberately NOT keyed on — it's user-settable on
    any host. The filesystem + kernel pair is the actually-distinctive
    signal.

  - Reuses the existing isGVisor() helper for the kernel half of the
    conjunction; no duplication.

Tests (4 new, vitest):

  - Positive: /.agents/AGENTS.md + 4.19.0-gvisor → gemini_managed_agent
  - Negative: gVisor alone (no /.agents/) → null (generic gVisor surface)
  - Negative: /.agents/AGENTS.md alone (no gVisor) → null (dev box false-positive guard)
  - Precedence: Gemini signal wins over a coincident CLAUDECODE env var

Empirical caveat: signal was gathered from a single sandbox. Re-confirming
across additional sandbox spins is a follow-up; the rule is conservative
enough (conjunction of two independent signals) that a single-spin
false-positive is unlikely, but a single-spin variance bug (e.g. some
sandbox flavors omitting one of the two markers) would surface as
under-detection rather than over-detection.

Source for signals: introspection write-up at
/tmp/gemini-sandbox-detection-signals.md (gemini-agent, 2026-06-09).

* docs(cli): reframe Gemini-managed-agent detection rationale (load-bearing vs guard)

gemini-agent's uniqueness analysis (FS-root + cgroup + netns + DMI + PID-1
introspection of env d59d6361, 2026-06-09) revealed the two signals are
NOT co-equal:

- /.agents/AGENTS.md is the uniqueness anchor — definitionally a
  managed-agent artifact, injected per-run by the platform, mtime
  tracks the interaction. Nothing in the generic Google-Cloud-on-gVisor
  universe (Cloud Run gen2, GKE Sandbox, Fly.io) mounts /.agents/.
- isGVisor() is a guard, not a second uniqueness signal. gVisor itself
  is shared with GKE Sandbox + Cloud Run gen2 — its real job here is
  ruling out a stray user-created /.agents/AGENTS.md on a non-sandbox
  host.

The original 3-spin work proved *stability* (signals consistent across
sandbox spins). This pass adds *uniqueness* — confirming the signals
discriminate Antigravity from the broader gVisor universe, not just
that they're reliably present. Stability ≠ uniqueness; both are
required for a correct detection rule.

Code unchanged (the AND-gate is sound). Docstring reframed so a future
reader doesn't mistake the conjunction for two independent uniqueness
signals. Also enumerated the markers NOT keyed on (with reasons), so
future contributors don't reach for them by naming inference.

Source: gemini-agent uniqueness analysis write-up.

* fix(cli): key Gemini managed-agent detection on /.agents/ mount, not optional AGENTS.md

The detector keyed on existsSync('/.agents/AGENTS.md'), but Google's Managed
Agents docs are explicit that AGENTS.md is OPTIONAL: an agent may declare its
instructions inline via system_instruction in agent.yaml and ship no AGENTS.md
file ("system_instruction and AGENTS.md are additive; both apply when present").
The platform auto-discovers the agent under the /.agents/ directory; skills
mount at /.agents/skills/ and AGENTS.md at /.agents/AGENTS.md only when shipped.

Keying on the file generalized only to templates that happen to bundle an
AGENTS.md (like HeyGen's own gemini-agent and Thor's reference). A managed agent
defined with inline instructions or a skills-only definition was a silent
false-negative. All three prior verification spins used our own AGENTS.md-bearing
template, so the gap was never exercised.

Broaden to the /.agents/ directory mount (still gVisor-guarded — false-positive
surface is unchanged) so skills-only and inline-instruction agents are detected.
Adds a regression test for the skills-but-no-AGENTS.md case. Documents the one
residual gap (pure inline-only, no skills/no AGENTS.md) that needs an empirical
spin to confirm.

* refactor(cli): tighten /.agents/ to a directory check + sync agent_runtime docs

Self-review follow-ups (no behavior change for real managed agents):

- isGeminiManagedAgent now requires statSync("/.agents").isDirectory() rather
  than existsSync("/.agents"), matching the documented "directory mount"
  contract. existsSync matched any entry (a stray file/symlink named /.agents),
  widening the gVisor-gated false-positive surface beyond what the comment
  claimed. Tests now mock statSync accordingly (and drop a dead /.agents/skills
  mock clause the code never read).
- system.ts: the agent_runtime doc comment hard-coded the vendor list and said
  "detected by env-var existence only" — both stale once a filesystem/kernel
  detector (gemini_managed_agent) exists. Point at the AgentRuntime union and
  note the filesystem-marker case instead.

Miguel Ángel 036b991cbb fix(runtime): preserve authored muted attr; clean up WebAudio on end (#1319)
onSetMuted/onSetMediaOutputMuted set el.muted = effective on every
<video> and <audio> element. When the bridge sent onSetMuted(false),
it unmuted avatar <video muted> elements whose baked-in lip-sync audio
should never play — causing double audio alongside the separate TTS.
Fix: el.muted = effective || el.defaultMuted.

AudioBufferSourceNode fires 'ended' when playback completes naturally,
but _activeSources was never cleaned up. This kept isActive() true
permanently, which force-muted all HTML audio elements via the
outputMuted flag in syncRuntimeMedia — causing audio to disappear
after the WebAudio buffer finished (~5s for short TTS clips).

Add onended listener that removes the source from _activeSources and
restores el.muted to its pre-WebAudio value. All side-effects are
guarded by idx !== -1 so a stale ended event after stopAll() is a
no-op and cannot clobber bridge state set between stop and the async
event delivery.

Miguel Ángel f0b499b582 fix(studio): keyframe bug fixes — gate delete hooks, fix value corruption, gesture recording (#1314)
- Gate stripStudioEditsFromTarget/bakeVisibilityOnDelete behind a
  stripStudioEdits flag on the delete mutation type so they only fire on
  user-initiated deletes, not on internal delete-then-recreate drags.

- Add bakeVisibilityOnDelete to the remove-all-keyframes handler so
  elements with CSS opacity:0 stay visible after collapsing keyframes.

- Fix integer rounding in readAllAnimatedProperties: use 3-decimal
  precision for visual properties (opacity, scale, rotation) instead of
  Math.round which corrupted mid-fade values to 0.

- Guard VISUAL_BASELINE against cross-tween contamination by querying
  __timelines for properties animated by other tweens on the same element.

- Harden bakeVisibilityOnDelete: reverse-scan keyframes for the last one
  containing opacity, guard against relative values (+=/-=/*=), and add
  Number.isFinite check.

- Fix falsy-zero doubling in drag commit: replace || fallback with
  Number.isFinite so a base GSAP position of 0 is correctly preserved.

- Fix gesture recording sign inversion: remove pointerElementOffset
  subtraction from dx/dy formula and instead apply it once to basePosition
  so the element center tracks the pointer.

- Fix TypeScript build errors in gsapSoftReload.ts (6 double-casts).

- Strip all diagnostic logs from production code.

Miguel Ángel 3a72aa528d fix(engine): add epsilon to frame index floor to prevent IEEE 754 boundary duplicates (#1318)
## Summary

Fixes #1317 — systematic duplicate+skip video frames when clip `data-start` is aligned to the output frame grid.

### Root cause

`Math.floor(localTime * fps)` in `getFrameAtTime` produces off-by-one errors when the product lands exactly on an integer boundary due to IEEE 754 float noise. For example, `0.28 * 25 === 6.999999999999999` instead of `7`, causing `Math.floor` to return 6 (duplicate of previous frame) instead of 7.

### Fix

1. Add `1e-9` epsilon before flooring: `Math.floor(localTime * fps + 1e-9)` — nudges boundary values like `6.999999` to `7.000000` without affecting mid-frame values.
2. Include `mediaStart` in the frame index computation so trimmed clips (`data-media-start`) map to the correct extracted frames.

Both call sites fixed: `getFrameAtTime()` (public API) and the `FrameLookupTable.getFramesAtTime()` bulk lookup.

### Reporter's measurements (before fix)

| Case | Duplicates (of 351 frames) |
|---|---|
| Source file | 1 |
| data-start="0" | 14 |
| data-start="230.44" (production) | 127 |
| data-start="0.02" (half-frame offset workaround) | 1 |

## Test plan

- [x] 4 new regression tests for IEEE 754 boundary precision
- [x] No duplicate frames when data-start is grid-aligned (25fps)
- [x] Monotonically increasing frame indices across 100 frames
- [x] Correct frame at the `0.28 * 25` boundary (frame 7, not 6)
- [x] `mediaStart` correctly offsets frame index
- [x] Typecheck clean

Miguel Ángel 8133d9346e fix(producer): don't mix audio from muted videos into the render (#1322)
* fix(producer): don't mix audio from muted videos into the render

The auto-detect audio block checked ext.metadata.hasAudio (file has
audio track) but not video.hasAudio (element declares itself audible).
A <video muted> whose source file contains audio leaked that audio
into the final render at full volume.

Add video.hasAudio guard so only audible elements contribute audio.

* test(producer): add unit tests for muted video audio guard

* fix: format

8fcbb63a37 docs(readme): swap hero media to hyperframes-logo-motion (#1315)
* docs(readme): swap hero media to hyperframes-logo-motion

Replaces the prior hfgif-1280.webp hero with a new logo-motion clip
Bin trimmed for the launch. Converted the source MP4 to animated webp
(the existing hero's format) so it auto-plays in the GitHub README the
same way the old one did - MP4 sources don't render inline or autoplay
in <img> tags.

- New asset: static.heygen.ai/hyperframes-oss/docs/images/
  hyperframes-logo-motion-1280.webp (1280x720, 85 frames, 199KB)
- ffmpeg conversion: scale=1280, libwebp_anim, q=80, loop=0

* fix(studio): format 5 hooks files (oxfmt)

* style: remove unused imports in studio hooks (pre-existing lint failures)

CI Lint on main was already failing with 5 unused-import errors in
packages/studio/src/hooks/. Removed the unused symbols to unblock the
README hero PR's CI:

- gsapRuntimeBridge.ts: resolveTweenStart, resolveTweenDuration
- useGsapScriptCommits.ts: usePlayerStore
- useTimelineEditing.ts: PatchTarget (type-only)
- gsapDragCommit.ts: readGsapProperty

Bundled into the README PR per James's request to fix CI in-place.

* test(studio): add childRects: [] to DomEditOverlay test mock

useDomEditOverlayRects' return type added a childRects: OverlayRect[]
field; the DomEditOverlay test's mock didn't get updated and was
returning an object without it, so DomEditOverlay.tsx's
'childRects.length > 0' check threw TypeError on undefined.

One-line mock-vs-hook contract realignment.

* test(studio): drive player-store currentTime in selection-hydration test (#1311 follow-up)

The 'hydrates seek first, preserves the initial url state, then restores
selection' test was failing because PR #1311 (keyframes feat) changed
useStudioUrlState to read currentTime from the player store via
usePlayerStore((s) => s.currentTime), removing it from the hook's prop
shape. The test was still trying to drive currentTime via the harness
prop, which is now a no-op — so the selection-hydration useEffect's
time-stability guard

  Math.abs(currentTime - stableTimeRef.current!) > 0.05

never passed (store currentTime stayed at 0 while stableTimeRef caught
the 4.2 seek target). buildDomSelectionFromTarget was never reached,
applyDomSelection was never called, and the assertion got 0 calls.

Fix: setState the store's currentTime to 4.2 ahead of the rerender so
the hook's selector picks it up and the time-stability guard passes.
Harness prop kept as-is — it's a no-op but doesn't hurt.

Pre-existing failure on main HEAD 81416ab3; surfaced as CI gate on the
unrelated docs/readme-hero-motion-update PR.

* test(studio): stub getBoundingClientRect + flush RAF in DomEditOverlay test

The 'renders selected bounds right after clicking a movable selection'
test asserts the selection box appears after pointerdown, but happy-dom
returns 0 for newly-created elements' getBoundingClientRect. The
overlay's compRect updates via a RAF loop that early-returns when iframe
width is 0; the keyframes PR a468550f added a compRect.width > 0 guard
to the selection-box render path, so compRect=0 silently gates the box
off and the assertion fails.

Stub Element.prototype.getBoundingClientRect to return 800x450 for the
test, and flush two RAFs after render so the compRect state update lands
before the pointerdown assertion. Restore the prototype at test end.
