* feat(core): add param-substitution utility for GSAP timeline inlining
U1: clone + shadow-aware identifier substitution over acorn ESTree, plus
provenance tagging and a GsapProvenance type. Foundation for resolving
helper/loop-built timelines in the read parser.
* feat(core): inline helper-built and bounded-loop GSAP timelines
U2: expansion pre-pass that rewrites the analysis AST so a helper called N
times, a literal-bounds for-loop, a for-of, or a forEach over an inline array
each become concrete per-call/per-iteration tl.* statements with substituted
positions and provenance tags. Transitive timeline-building detection, safe
declaration dropping, depth/iteration caps; unresolvable constructs untouched.
* feat(core): resolve computed GSAP timelines in the read parser
U3: parseGsapScriptAcorn runs the inlining pre-pass before analysis, so
helper-built and bounded-loop timelines resolve at true positions with
motionPath arcs recognized; each tween carries provenance. Expansion order is
stamped so cloned tweens (sharing source loc) sort correctly. Read path only —
parseGsapScriptAcornForWrite is untouched, degrades to current behavior on
failure. The add-to-basket addCycle case now yields 7 resolved animations.
* feat(studio): runtime-authoritative keyframes for dynamic timelines
Phase 2 (U4-U6): the live-runtime scanner returns tween-relative keyframes
with per-tween timing and converts them to clip-relative when given clip dims,
fixing the timeline-vs-clip-relative bug; it extracts motionPath into arcPath
(shared buildArcPath) so the Arc Motion panel activates for data-driven arcs;
the cache leaves statically-unresolvable tweens to the runtime scan. Exempts
the pre-existing large useGsapTweenCache effects from fallow health (file-level,
like files.ts) rather than suppression comments.
* feat(studio): surface keyframe editability from provenance
U9: editabilityForProvenance(provenance) -> direct|unroll|override (core,
re-exported from the acorn subpath). A ComputedTweenNotice component shows an
unroll affordance for helper/loop tweens (wired in U10) and an overrides note
for dynamic ones. Extracts the shared GsapAnimationEditCallbacks interface to
remove section/card prop duplication.
* feat(core): lint understands computed timelines (acorn parser)
U7: the GSAP lint rule now loads parseGsapScriptAcorn (which inlines helpers
and bounded loops) instead of the recast parser, so overlapping_gsap_tweens and
related findings reflect true resolved positions for computed timelines — and
keeps recast out of the lint graph entirely. Literal compositions are
unchanged (parity), all 182 lint tests pass.
* docs: document the computed-timeline keyframe editing model
U8: keyframes.mdx explains that helper/loop/data-built timelines display
correctly, and how each is edited — literal (direct), helper/loop (unroll to
edit), dynamic (composition overrides). Nothing is permanently locked.
* feat: unroll computed timelines into literal tweens (U10)
Adds unrollComputedTimeline (core): serializes a parsed timeline's resolved
animations back to literal tl.* statements (arc/keyframe-aware) and surgically
replaces the top-level helper-call/loop statements that produced them via
magic-string, dropping dead helper declarations — a verified visual no-op.
Wires an unroll-timeline studio-api mutation and threads onUnroll to the
AnimationCard 'Unroll to edit' button. Exempts panel files whose inherited
fingerprints shifted from the prop threading.
* feat(runtime): declarative keyframe override layer for dynamic tweens (U11)
Adds applyKeyframeOverrides: fetches a gsap-overrides.json sidecar and applies
explicit per-tween value overrides to the live timeline (keyed by selector +
tween ordinal), invalidating so GSAP re-reads them — the deterministic,
render-safe mechanism (preview + headless) for persisting edits to dynamic
tweens that can't be unrolled. Mirrors the shipped caption-overrides pattern;
wired into runtime init alongside applyCaptionOverrides.
* refactor: drop the keyframe override layer; rely on unroll + source
Removes the gsap-overrides.json sidecar (runtime apply + init wiring + tests):
it solved a near-nonexistent case (HyperFrames is deterministic, so genuinely
unresolvable dynamic tweens barely exist) and introduced a parallel
persistence path outside the composition. The real cases are covered without
it — const/variable values resolve statically, helper/loop tweens unroll to
literals and then edit in-script (single source of truth). Renames the
editability strategy 'override' -> 'source' (edit in the Code tab) and updates
the notice + docs accordingly.
* fix(studio): drag outside tween range creates new keyframe, picks nearest tween
Fixes the GSAP drag intercept to pick the position tween closest to the
playhead (not the one with the most keyframes), and when dragging outside all
tweens' ranges, creates a brand-new keyframed tween instead of destructively
extending/replacing the nearest one. Reads the runtime position at the tween's
start time (via iframe seek) so convert-to-keyframes produces correct 0%
keyframes that preserve the interpolation from preceding tweens.
* fix(studio): drag outside tween range creates new keyframe, picks nearest tween
Also reverts all fallow health.ignore additions — pre-existing complexity in
touched files is accepted as inherited, not suppressed.
Add a "Video Components" overview to the docs site — an entry point to the
50+ catalog blocks and components: what they are, how to install and wire
them, and how to contribute a new one. Wire it into the Guides sidebar.
* feat: add video frame format render option
* refactor: single source of truth for video-frame-format allow-list
Addresses PR review (Via) on #1481: the ["auto","jpg","png"] set was
declared three times — render.ts (VIDEO_FRAME_FORMATS), server.ts
(inline includes), and renderConfigValidation.ts
(ALLOWED_VIDEO_FRAME_FORMATS) — three boundaries to update when a new
extraction format lands.
Hoist the constant + a reusable `isVideoFrameFormat` type guard into
@hyperframes/engine (where VideoFrameFormat is defined) and route all
three call sites through them. Behavior unchanged; also drops two
`as RenderConfig[...]` casts in favor of the guard (narrowing over
assertion, per repo TS conventions).

* feat(cli): support OpenRouter as an alternative vision provider for capture captioning
`hyperframes capture` could only enrich asset descriptions with Gemini vision,
which requires a Google API key. Add OpenRouter as an alternative so users
without Google access can caption via any vision-capable model through one
unified key.
Provider is selected by which key is present: OPENROUTER_API_KEY → OpenRouter
(OpenAI-style /chat/completions with an image_url data URI), else
GEMINI_API_KEY/GOOGLE_API_KEY → Gemini (unchanged), else DOM-only as before.
OpenRouter wins if both are set. Default model is google/gemini-3.1-flash-lite
(the OpenRouter analog of the Gemini path's existing 3.1-flash-lite tier),
overridable via HYPERFRAMES_OPENROUTER_MODEL.
Both vision call sites — the image loop and the rasterized-SVG loop — route
through a single `captionOne` dispatcher, so the new provider works for SVGs too
(the original PR #840 only patched the image loop, which would have left
OpenRouter-only users with crashing SVG captioning). The OpenRouter path checks
res.ok and surfaces the status/body on failure.
Reimplements #840 (which was unmergeable: saved with a UTF-8 BOM + CRLF so
GitHub rendered it as a binary diff, used `any`, reused the Gemini model env
var, and had a hallucinated default model id).
- Adds unit tests for the OpenRouter path (happy path, graceful degradation on
non-OK status, no-key skip).
- Documents OPENROUTER_API_KEY in the website-to-video guide and the CLI capture
reference.

* test(cli): fix typecheck in OpenRouter caption test — capture request without `as`
The test cast `fetchMock.mock.calls[0]` to a tuple (TS2352: `[] | undefined`
doesn't overlap `[string, RequestInit]`), which failed the Typecheck CI job.
Capture the url/init inside the typed mock and assert via `new Headers()` +
`typeof` narrowing instead — no `as` assertions (which the repo bans anyway).

Adds a Code Animations catalog section — 9 self-contained, installable blocks:
morph, snippet-flight, typing, diff, highlight, scroll (DOM/GSAP) and 3d-extrude,
shader-dissolve, particle-assemble (WebGL). Each block ships only its own effect and
renders deterministically (paused GSAP timeline seeked per frame, seeded RNG, no
render-time data fetch). Wires the catalog nav, registry.json, a new code-animation
Studio category, and preview assets.
Extend `inspect` to verify motion intent against the same seeked timeline
the renderer uses, catching render-≠-preview bugs that layout sampling can't:
entrance reveals the seek skips, broken stagger order, off-frame drift, and
frozen shots.
A `*.motion.json` sidecar next to the composition opts in (auto-discovered,
no flag, no authoring-framework changes); without one, inspect is unchanged.
inspect seeks a dense grid over the asserted selectors, builds an
element × time matrix of {rect, opacity, visible} plus per-scope liveness
signatures, and evaluates four assertions in Node:
appearsBy -> motion_appears_late
before -> motion_out_of_order
staysInFrame -> motion_off_frame
keepsMoving -> motion_frozen
A selector matching nothing is reported as motion_selector_missing rather
than silently passing. Findings reuse the LayoutIssue shape and flow through
the existing dedupe/collapse/limit/format pipeline and JSON envelope; they
are errors by default, so a failed assertion fails the run.
The motion pass runs in the same Chrome session as the layout audit (no extra
launch) and only when a sidecar is present.
Make /hyperframes the single entry skill and bring the docs back in sync with
the #1349 skills refactor.
Skills:
- Rename hyperframes-read-first -> hyperframes so the leaderboard-tracked
/hyperframes is the entry/router skill; description leads with "READ THIS
FIRST" to preserve the read-first intent. Update all references across
CLAUDE.md, AGENTS.md, CLI templates, test script, and workflow SKILLs.
Docs (closes the quickstart confusion in #1428):
- quickstart + prompting: replace the dead standalone runtime slash commands
(/gsap /lottie /three /waapi /animejs /css-animations /tailwind) with the
real surface; document the picker as required core skills (8) vs optional
workflows, with --all as the install-everything shortcut.
- frame-adapters: map every runtime to /hyperframes-animation.
- packages/cli: /tailwind -> /hyperframes-core; rewrite the skills-include
blurb around the current domain skills.
- copilot-cli/pipeline/migrating-to-lambda: /hyperframes is the router; the
composition contract lives in /hyperframes-core. Fix a dead /gsap example.
- antigravity: stop listing gsap/ and tailwind/ as separate skill dirs.
- contributing/catalog: /contribute-catalog -> /hyperframes-registry.

The layout audit only reported boxes that overflow their container; text
that fits perfectly but is painted over by a later sibling or overlay was
never caught. Add a text_occluded check that sweeps a grid across each text
box (three rows x nine columns) and, via elementFromPoint, flags text whose
topmost element is an unrelated opaque element (raster content, background
image, or a solid background at near-full opacity). Low-opacity overlays
such as scrims and grain are exempt. Opt out of intentional layering with
data-layout-allow-occlusion.
The two *.browser.js audit scripts are added to the fallow entry list: they
are injected by path via page.addScriptTag, so they have no import-graph
referrer.

The layout audit compares each element against its container, so two text
blocks that collide with each other — neither overflowing its own box —
render unreadable yet pass clean. Add a content_overlap check that pairs up
the solid text blocks and reports any two whose boxes intersect by more than
a fifth of the smaller box. Watermark-style text (low colour alpha) is
decorative and exempt; opt out of intentional stacking with
data-layout-allow-overlap.

* feat(studio,cli): music beat detection with timeline guides + headless beats CLI
Beat detection for music tracks: the Studio draws beat guides on the active
track, beats are user-editable and persist to a project file, and a new
`hyperframes beats` CLI generates that file headlessly before the Studio opens.
Detection lives in @hyperframes/core/beats (shared by Studio + CLI): an energy
onset detector cross-validated with bpm-detective, regularized to an octave-
aligned grid, silence-gated, with per-beat loudness. Music-only — an
<audio data-timeline-role="music"> is analyzed; voiceover is excluded.
Studio: green beat lines + draggable dots on the selected track; add at playhead,
drag to move, double-click to delete (audio scrubs); edits persist to
beats/<audio>.json and are undoable (interleaved with file history).
CLI: `hyperframes beats [dir]` runs the same detection in headless Chrome
(prebuilt browser bundle in dist) and writes the beat file.

* feat(studio): timeline beat-grid + zoom UX refinements
- Center-anchored magnify: zooming via the toolbar/slider keeps the time
at the viewport center fixed instead of anchoring at the left. Pinch
still anchors at the cursor.
- Move-snap to beats: dragging a clip snaps whichever edge (start or end)
is nearest a beat, matching the existing resize-edge snapping.
- Beat lines on track backgrounds: faint full-height beat lines now paint
behind the clips on every track lane (brightness scales with loudness);
the green dots stay on the active track's top bar.
- Waveform follows zoom: bars fill the full clip width and resample the
windowed peaks, so the waveform stretches with zoom instead of stopping
partway across a widened clip.
- Beat dots centered in the top bar: align the dot band to the clip top
(CLIP_Y) so the dots sit centered in the dark bar instead of being
bisected by the clip's top border.

* fix(studio): preserve media sourceDuration across element re-derivation
Moving a non-music clip re-derived the timeline elements into fresh
objects whose sourceDuration the DOM scan hadn't loaded yet. The async
probe skips srcs already in its cache, so the value was silently
dropped — trimFractions then returned no window and the trimmed music
waveform reset to the full source pinned at the track start.
Re-apply the cached probe duration synchronously on every derivation
(applyCachedSourceDurations) and extract the async probe loop into
probeMissingSourceDurations to keep useTimelinePlayer within the file
size limit.

* feat(studio): skip beat-snap on the music track, highlight move-snap target
The music track defines the beats, so moving or trimming it no longer
snaps to its own beats (isMusicTrack guard on both the move and resize
snap paths).
Moving another clip snapped only on drop with no cue. snapMoveStartToBeat
now also returns the beat it will snap to; BeatBackgroundLines draws that
beat's line as a bright neon-green glow while the clip's edge is within
the snap region, so the target is visible before drop.
Also drops .commitmsg.tmp, accidentally committed via git add -A.

- Dragging a beat dot now hides the playhead guideline (new beatDragging

scrub and clutter the beat being moved.
- Beat dots render on the selected track, falling back to the music track
when nothing is selected.

CodeQL js/polynomial-redos: the lazy `.+?` followed by an optional

* fix(studio,core,cli): review hardening for beat detection + timeline UX
- playerStore.reset() now clears beat state (analysis, edits, undo/redo,
persist) so a project switch can't apply the previous project's beats,
undo stack, or file-writer to the new one.
- removeUserBeat returns the same reference on a no-op, and delete/move beat
actions skip committing when nothing changed — no more phantom undo
entries / debounced writes for no-op edits.
- regularizeBeats bails to raw onsets when the (octave-misread) tempo would
produce a sub-125ms grid, avoiding a tens-of-thousands-of-beats freeze.
- parseBeats clamps strength to [0,1] and rejects non-finite time/strength,
so a hand-edited file can't feed NaN into the gamma curve (Math.pow on a
negative base) and blank out beat markers.
- Start-edge beat-snap now also requires duration >= minDuration, matching
the end-edge guard, so a rightward snap can't collapse the clip.
- Center-anchor zoom effect always consumes its skip flag, so a pinch that
produced no pps change can't leave it stranded and skip the next zoom.
- Headless beats analyzer projects to {beatTimes,beatStrengths,bpm,confidence}
before returning, so page.evaluate no longer serializes the full decoded
PCM (channelData) across the CDP boundary.

* refactor(skills): split prep/validate + extract hierarchy gate (PLV/FE/pr forks)
Addresses PR #1349 review (#1.1 complexity reduction). Applied across all three
script forks (product-launch-video, faceless-explainer, pr-to-video) and verified
output-preserving: group_spec.json is byte-identical HEAD-vs-tree on golden
fixtures, and all validator outputs match (incl. pr-to-video's TTS word-budget).
- split validate.mjs -> validate-narrator.mjs + validate-section.mjs (the merged
dispatcher had no shared logic); all call sites updated
- split prep.mjs into lib/prep-{log,assets,section,design,sfx}.mjs, keeping the
same CLI entrypoint (PLV 942->520, FE 1043->623, pr 1074->653 lines)
- extract the hierarchy classifier into lib/hierarchy-gate.mjs and add an optional
authoritative **Hierarchy:** anchor (collapses the risk check to a schema read
when the planner declares it; prose classifier kept as the no-anchor fallback)
- nits: HF-SCENE-CLIP marker + drift guard between assemble-index and transitions;
tighten wait-bgm failure pattern (out of range -> index out of range/out of bounds);
document verify-output DUR_TOLERANCE_S sourcing
- document the **Hierarchy:** anchor in each fork's visual-design guide
Each fork keeps its own divergent logic verbatim: FE/pr use the decoupled-continuity
model (required break/continue anchor, morph intent, continue-runs of up to 3),
pr-to-video keeps its per-scene TTS word-budget in the narrator validator.

The 34 MB ppmattingv2 ONNX was committed as a raw blob (added before the
*.onnx LFS rule could catch it), making it 97% of this PR's repo-size growth
and permanent history weight once merged. Per size review on the PR:
- blob removed from the tree; hosted on the model-assets-v1 GitHub release
(asset sha256-verified byte-identical after upload)
- matte.cjs resolves: MATTE_MODEL env -> legacy bundled copy if present ->
~/.cache/hyperframes/matting/ with one-time sha256-pinned download (same
pattern as the CLI background-removal manager pulling u2net from rembg's
release bucket); same-dir .part temp + atomic rename
- new `matte.cjs --ensure-model` pre-warm flag; SKILL.md dependency note
updated (offline hosts: pre-place at the cache path or set MATTE_MODEL)
E2E verified: fresh-HOME download (sha match), cache hit (silent), missing
MATTE_MODEL path (exit 3). Author-time fetch only — render path untouched.
NOTE: merge this PR via SQUASH — a merge/rebase merge would carry the raw
blob from earlier branch commits into main history permanently.

* refactor(hyperframes-animation): make examples self-contained, drop 39 MB examples/assets
Repo-size follow-up on PR #1349 (the size review undercounted: beyond the
onnx, examples/assets held two raw videos — a 4K background texture and a
26s HEVC showcase — plus logo png and avatar/brand images, ~39 MB total,
none LFS-tracked, referenced only inside these examples).
- assets/ deleted outright; no external path coupling (verified).
- 6 consuming examples patched to the corpus's own placeholder idiom
(workflow-approve-press already demos video-less fallback; proof-logo-chain's
header CLAIMED inline-SVG fallbacks that didn't exist — now true):
* 3 logo <img> sites -> inline-SVG "HF" mark (CSS selector retargeted)
* hook-counter-burst: bg <video> dropped; designed .bg gradient carries
* metric-video-text-pivot: showcase <video> dropped; designed .video-scene
carries; escaped <video> re-add snippet kept as a comment (literal
<video in comments trips the lint media scanner)
* proof-logo-chain: avatars -> CSS initials circles (deterministic
index-derived hues), brand avifs -> CSS text chips via --brand-name,
ASSETS config -> CREATOR_INITIALS
- HEVC removal also fixes a real portability bug: headless Chromium on Linux
generally lacks HEVC decode, so that example could render frozen.
- Gates: hyperframes lint 0 errors x13, validate (headless Chrome) 13/13 pass
with assets gone.
PR added-file weight drops ~49.5 MB -> ~10.6 MB. Squash-merge note from
ca6ea3a3 still applies (blobs live in branch history).

* style(hyperframes-animation): oxfmt the 4 SVG-placeholder examples
CI Format runs `oxfmt --check .` repo-wide (oxfmt formats HTML too); the
lefthook format hook's glob misses skills/**/*.html, so the inline-SVG
edits from the de-assetization commit slipped through pre-commit unformatted
and failed CI Format + every workflow's Preflight (lint + format) gate.
Attribute-wrap only; lint 0 errors + validate re-pass on all 4.

* fix(cli): clear fallow audit gate (PR #1349 CI)
Two parts:
- validate.ts: replace the inline static-file server with the shared
serveStaticProjectHtml util (same one snapshot.ts / layout.ts use).
Removes both fallow clone groups and picks up the util's loopback-only
bind + path-traversal guard that the inline copy lacked.
- Suppress fallow complexity findings on guard-ladder I/O orchestration
in files this PR touches (capture/, whisper/, build-copy.mjs,
staticProjectServer.ts). These units are deliberate sequential
guard chains (SSRF checks, byte caps, download budgets) where
decomposition to cyclomatic <=5 per unit would hurt readability;
same suppression pattern already used across packages/studio.
Fallow audit now exits 0 against origin/main; CLI suite 719/719 green.

* feat(embedded-captions): sync live skill — 22 new themes, Standard retired, anchor default
Brings the branch up to the live skill state (commits through 761e520):
- 22 ported theme DNAs across mechanical/light/craft families (flap/LED/VHS/
arcade/dossier, laser/thunder/hologram/biolume/aurora/spectrum, papercut/
popup/chalkboard/graffiti/brush/inkwater/ransom + earlier 5 constitutions)
- themes engine: 18+ body paradigms & hero setpieces, char-widths.json glyph
metrics, stroke-draw family on shared gen-stroke-path registration
- Standard mode retired; 'anchor' quiet rail theme is the conservative default
- 54-template legacy library + make-standard archived out of tree
- matting via hyperframes remove-background (PP-MattingV2 onnx dropped)
- SKILL.md description retightened under the 1024-char lint; suite oxfmt'd
- CDPR fan-kit source SVG kept out of tree (gitignored; metrics json suffices)

* fix(embedded-captions): clear CI lint — dead declarations + backtick rephrase
oxlint: nLines/waveTop/p (+orphaned h) left by the port batches in
make-theme.cjs. skill-lint: `>180`/`<br>` inline backticks read as shell
redirection; rephrased without changing meaning. Fixture regressions green
(laser/anchor/ransom recompile clean).

* fix(embedded-captions): e2e cold-start findings — VFR matte desync +6
Mirrors the live skill fix set: avg-fps probe + VFR CFR-normalize + bidirectional
frame parity in matte.cjs (ghost double-subject), ensureFontSize hero guard,
preview-frames gsap-respond fix, quote-agnostic font embedding, heroless themes +
calm-register growth cap + hero maxHold, transcript schema validation, honest
theme gate reporting. Verified: 19/19 fixture regression, C1/T3/T4 re-rendered.

* docs(skills): quote frontmatter descriptions for YAML safety
Wrap the description: values in embedded-captions, remotion-to-hyperframes,
and website-to-video SKILL.md frontmatter in quotes — the unquoted strings
contain colons and embedded double quotes that can break YAML parsing.
oxfmt normalizes the two with embedded quotes to single-quoted form.

HyperFrames MCP is rolling out to Grok this week. Add Grok alongside
Claude.ai and ChatGPT: new setup tab (catalog search + custom-URL
fallback), and include it in the title, intro, progress-notification
host list, issue-report host list, and widget-supported host list (Grok
renders MCP widgets).
Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
TTS/voiceover is disabled in the hosted MCP, so the public MCP guide no
longer reflects current functionality. Remove all voice/TTS mentions:
- "voice generation" from the compose agent's built-in skills list
- "voice selection" from the compose tool description
- "voice / TTS" from the "what the hosted MCP wraps" section
- "Selecting voice and style..." progress-notification examples
- brand-voice asset reference (agent can't synthesize speech anymore)
Also add guides/mcp to the Guides sidebar group — the page existed but
was only reachable by direct URL, not from the nav.

Plan documents are working artifacts that shouldn't be committed.
Removes three plans that were accidentally tracked and adds
docs/plans/ to .gitignore to prevent future occurrences.
Compositions are now self-contained: the compiler captures font files
and embeds them as woff2 data URIs, eliminating silent render-time
fallback when the render environment lacks the author's fonts.
Resolution order (each tier falls through to the next):
1. Existing @font-face → use as-is
2. Bundled alias (38 cross-platform mappings) → embed data URI
3. Google Fonts → fetch, cache, embed
4. Local system font → locate on OS, compress to woff2, embed
5. Local @font-face paths → read file, compress, inline as data URI
6. External CDN stylesheets → fetch CSS, extract @font-face, inline
7. Alias map fallback → closest bundled equivalent
8. Actionable error with guidance
Key changes:
- System font locator (macOS/Windows/Linux) with path-bounding and
symlink defense (realpathSync + O_NOFOLLOW)
- woff2 compression via wawoff2 (WASM, cross-platform)
- Multi-weight/style variant capture with length-sorted token matching
- External stylesheet inlining with SSRF defense (assertPublicHttpsUrl,
HTTPS-only, private-host blocking, 2MB cap, 4-concurrent limit)
- Studio auto-import via GET /fonts/file API + renderAliasFor() derived
from shared FONT_ALIAS_MAP (no more hand-curated drift)
- failClosedFontFetch throws on unresolved fonts in distributed renders
- Single source of truth: @hyperframes/core/fonts/aliases
- system_font_will_alias lint rule (escalates to warning for distributed)
- Default to Inter + JetBrains Mono in templates and CSS reset
* feat(gcp-cloud-run): add Google Cloud Run + Workflows distributed render adapter
Adds @hyperframes/gcp-cloud-run, the GCP counterpart to @hyperframes/aws-lambda
(issue #932). The OSS distributed primitives (plan, renderChunk x N, assemble)
are unchanged; this package is the storage/compute/orchestration glue.
Package: Cloud Run handler (one image, three actions), runs under bun; GCS
transport; in-image chrome-headless-shell resolver; client SDK
(renderToCloudRun, getRenderProgress, deploySite, computeRenderCost); Dockerfile;
Cloud Workflows definition; Terraform module; CLI cloudrun
deploy|sites|render|render-batch|progress|destroy with --output-resolution and
--strict-variables; 62 unit tests + docs + live smoke script.
Shared extraction (removes ~640 lines of adapter duplication): move the
cloud-agnostic config validator + content-hash into producer/distributed; both
adapters import them. Validated end-to-end on GCP at 37.4 dB PSNR vs baseline.

* fix(cli): resolve @hyperframes/gcp-cloud-run in the CLI build + root build
The CLI bundle (esbuild) couldn't resolve `@hyperframes/gcp-cloud-run/sdk`,
failing Build/Typecheck/CLI-smoke (and the perf/windows/regression jobs that
build first). Mirror the aws-lambda handling: mark the gcp adapter + its /sdk
subpath external in tsup.config.ts with a source alias, and add gcp-cloud-run
to the root `build` filter so its dist exists for publish + runtime.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(ci): copy gcp-cloud-run manifest in Dockerfile.test for frozen install
The regression test image runs `bun install --frozen-lockfile` after copying
each workspace package.json individually. The CLI now depends on
@hyperframes/gcp-cloud-run (workspace:*), so the frozen install fails to
resolve it unless its manifest is present. Add the COPY line.

* feat(cli): add machine-sizing flags to `cloudrun deploy`
Closes the parity gap with `lambda deploy` (which exposes --memory etc.).
`cloudrun deploy` now threads --cpu, --memory, --max-instances, and --timeout
into the Terraform apply; omitted flags keep the module defaults
(4 vCPU / 16Gi / 100 instances / 3600s). For finer control, apply the module
directly.

* fix(gcp-cloud-run): address PR review (security, waste, limits, alerts)
- server.ts: bucket-allowlist guard no longer fails open silently. Unset env
logs a one-time WARNING; "*" is an explicit opt-out; otherwise it enforces.
- server.ts: stop double-shipping audio.aac. It already rides in the plan
tarball every consumer downloads, so drop the redundant standalone upload
(plan) + re-download/overwrite (assemble); assemble reads it from the untar,
falling back to a supplied AudioGcsUri for compat.
- server.ts: chunk extension via path.extname() instead of slice(lastIndexOf).
- workflow.yaml: clamp parallel concurrency_limit to math.min(chunkCount, 20)
— Cloud Workflows hard-caps concurrent iterations at 20.
- Dockerfile: pin bun (bun-v1.3.9) so an interop change can't silently break
the image rebuild.
- terraform: add min_instances var (default 0); add a workflow-failure alert
(finished_execution_count status=FAILED) alongside the request-count one.
- costAccounting: document that displayCost excludes GCS storage/egress.
Verified against the actual APIs: @google-cloud/workflows@4.4.0
ICreateExecutionRequest has no executionId (so the idempotency-token suggestion
isn't available in this client); Workflows concurrency cap is 20; failure
metric is workflows.googleapis.com/finished_execution_count (status label).
174 adapter tests pass, fallow/oxlint/oxfmt/terraform clean.

* fix(gcp-cloud-run): address round-2 review — error code + CFR forwarding
- workflow.yaml: rename the zero-chunk failure code PLAN_TOO_LARGE →
PLAN_PRODUCED_ZERO_CHUNKS. The old code implied a size-ceiling breach (the
opposite cause), misleading anyone triaging the alert.
- workflow.yaml: forward Config.cfr to the assemble step
(`Cfr: ${("cfr" in config) and config.cfr}`). It was read by the handler
but never sent, so exact-CFR was silently off for every Cloud Run render.
Uses the same `in`-operator guard already proven in the retryable predicate.

* fix(release): include gcp-cloud-run in set-version PACKAGES list
set-version.ts (driven by release:prepare) bumps an explicit package list to
the shared version on each release. gcp-cloud-run was wired into the build +
publish.yml but missing here, so a release would leave it at a stale version
and publish.yml would push the wrong version. Add it so the new package
version-bumps + publishes in lockstep with the others.

* feat(gsap): add innerText support to GSAP inspector for counter animations (#1244)
Adds 'innerText' as a supported GSAP property so number roll-up animations
(count-up from 0 to some value) are visible and editable in the GSAP inspector
panel.
- Add 'innerText' to SUPPORTED_PROPS in gsapConstants.ts
- Add label 'Counter Value', tooltip, and step constraint (1) in
gsapAnimationConstants.ts
The snap modifier that controls integer rounding is already preserved
verbatim via the EXTRAS_KEYS round-trip, so rounding behavior survives
edits without any additional UI changes.
Closes#1179
* feat(registry): add text-effects catalog section and morph-text component
Introduces a new "Text Effects" catalog section (below Effects) for text-focused visual components.
- Add `text-effects` BlockCategory to core registry types with violet color
- Add `text-effect` tag resolver in resolveBlockCategory (checked before generic `effect` tag)
- Tag caption-blend-difference, texture-mask-text, and morph-text with `text-effect`
- Update studio catalog order and color map to include text-effects
- Add morph-text component: gooey SVG threshold morph cycling through editable statements
using GSAP seekable proxy pattern for deterministic/seekable rendering

* chore(registry): add demo.html for morph-text catalog preview rendering
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix(registry): address PR review feedback on morph-text and text-effects
- Restore `effect` tag on caption-blend-difference and texture-mask-text
alongside `text-effect` so existing tag-equality searches/analytics still match
- Fix morphPause script fallback from "0.25" to "1.5" to match data attribute default
- Add Math.max(0, ...) guard to blur values (intent clarity)
- Add prefers-reduced-motion: skip morph and show first word statically
- Remove CATEGORY_ORDER record from useBlockCatalog; derive order from
BLOCK_CATEGORIES array (single source of truth, no drift)
- Add comment to demo.html documenting its purpose (catalog preview script only)
