- caption-emoji-pop: shadowForColor now builds its glow via color-mix()
instead of hex-pair slicing, so the strict 6-digit brand-color gate is
gone — any CSS color the sibling templates accept (#fff, rgb(), named)
now renders instead of silently falling back to the default palette
- caption-weight-shift: fitFontSize now sizes against the WIDEST split
line rather than the joined group text (two-line groups no longer shrink
unnecessarily), and avoidSingleWordGroups' merges re-check fitsInTwoLines
like makeGroups' first pass does (merged groups can no longer overflow
the split budget)
- all 5: hfApplyStageConfig clamps resolution to the published validator's
<=8192 bound (validator is optional pre-flight; unbounded stages OOM
render workers), and fit floors carry a comment documenting that the
minimum size is returned unverified by design

Two review findings on the caption-data runtime, applied to all 5 templates:
- hfValidate's version gate used Math.floor(Number(v)) > HF_CONTRACT_VERSION,
and Number("v2") is NaN — NaN comparisons are always false, so malformed
versions slid through with no unsupported-version signal. An explicit
Number.isFinite check closes it.
- hfBoot's sibling-fetch .then called hfAttach unconditionally; a manual
window.__HF_CAPTION_ATTACH__ call landing while the fetch or fonts.ready
was still pending got clobbered by the late boot payload. Boot now yields
if a timeline already exists.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
caption-highlight was already IIFE-wrapped; the other four leaked their
runtime (hfAttach/hfBuild/...) as script-scope globals. Harmless when boot
was synchronous, but the data-driven retrofit defers attach behind
fonts.ready + the sibling fetch — with two caption components pasted into
one composition document, every script finishes before any deferred boot
runs, the last script's definitions win the shared scope, and the first
component never registers its timeline (a renderer waiting on it hangs to
timeout). Wrapping each template's script keeps its internals private so
each boot attaches its own component. window.__HF_CAPTION_ATTACH__ remains
intentionally window-scoped (last-defined-wins).

hfApplyStageConfig (Block B, verbatim across all 5 retrofitted caption
identities) only ever set --hf-caption-primary/--hf-caption-accent when the
corresponding brand.primaryColor/accentColor key was present, with no else
branch to clear it when absent. Re-attaching a brand-less payload after a
branded one left the custom property (and any JS-cached color derived from
it, e.g. caption-pill-karaoke's hfColorActive and caption-emoji-pop's
hfAccentColors) stuck at the stale value instead of reverting to the CSS
fallback, violating idempotent re-attach.
Also removes caption-editorial-emphasis's dead .word--italic CSS rule and
CLASS_MAP.i entry — hfMakeBlocks only ever emits "n"/"e" tags, "i" was only
reachable via the old hand-authored BLOCKS literal this task replaced.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Both identities looped over every OTHER group/block to force its opacity
to 0 at each group's own start time, in addition to each group already
setting its own opacity to 0 at its own end. Since groups/blocks occupy
non-overlapping time windows and already own their full opacity
lifecycle, that loop was dead weight — but it made timeline construction
O(n^2) in the number of groups/blocks. Under the Task 7 stress transcript
(long, frequent "emphasis" words forcing near single-word blocks/groups),
n reached ~2000 and the page hung well past a 30s test timeout for both
identities.
Verified behavior-preserving: full templates.test.ts (41 tests, incl.
opacity/seek assertions) and the new limits.test.ts stress suite pass
against both identities after the removal.
Replaces the hand-authored BLOCKS literal with hfMakeBlocks, a heuristic that
groups words into blocks/lines from timing (pauses, punctuation, max words per
block) and hfIsEmphasisWord (long, non-stopword content words) to decide which
word gets the large Playfair Display emphasis treatment and its own slide-in
line. computeLineSize/buildBlocks/fitBlocks and timeline construction now live
inside hfBuild, closing over layout-scaled font sizes and widths. Adds the
shared Blocks A-E caption-data runtime (attach/gate/brand config) and the
.word/.word--emphasis CSS brand hook for --hf-caption-primary. This is the
last of the five caption identities to go data-driven.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Replaces the hardcoded RAW_GROUPS index-pair array with hfMakeGroups, a
real fitting/pause/punctuation-based grouper, and wires the component
into the shared caption-data runtime (validate/gate/attach). Adds CSS
brand hooks: .hl-word text color from --hf-caption-primary, .hl-word-bg
gradient from --hf-caption-accent (second stop via color-mix()).
Retrofits caption-emoji-pop onto the shared HyperFrames caption-data runtime
(Blocks A-D) and the emphasis heuristic (Block E), replacing the hardcoded
7-word emoji map, fixed KEYWORDS set, and TRANSITION_WORDS set with a
generic ~40-entry lexicon and HF_STOPWORDS/hfIsEmphasisWord. The component
now consumes brand.primaryColor (hfPrimaryColor) and brand.accentColor
(hfAccentColors) and rescales stage/font/emoji sizing to the runtime
resolution via layout.fontScale/scaleX/scaleY.

The flowchart and flowchart-vertical blocks read tl.labels["hold5"] back
from the timeline to schedule the "Pythom" -> "Python" typing correction.
The render compiler executes composition scripts under a GSAP proxy whose
timeline exposes no readable .labels map, so this line throws
("Composition script failed ... Cannot read properties of undefined
(reading 'hold5')") before window.__timelines is assigned. The block is
never registered: renders show only the dotted-grid background and every
render pays the 45s sub_timeline_readiness_timeout.
Use GSAP's own label-relative position syntax ("hold5+=<offset>") instead,
matching every other step in these files. Identical timing, no .labels read.
Verified with hyperframes@0.7.60 render: block was blank before, animates
after; the readiness timeout disappears.
* docs(registry,skills): surface code-highlight 0-based indexing and opacity-reveal sweep guidance
From the 2026-07-14 CLI feedback digest (skills-owner action): a user
building code teaching videos hit two authoring gaps.
1. code-highlight's `line` is intentionally zero-based (`line: 1` =
second displayed line) but the warning lived only in pr-to-video's
code-vocabulary reference — nowhere an author actually touches the
value. Call it out at the block-use sites: the `__BLOCK` declaration
itself, the registry-item description, and the motion-graphics
catalog map.
2. Opacity-only code-typing tripped `sweep_static` for that user, who
worked around it with a slow host y-drift. The sweep fingerprint
does include per-element opacity, so document the actual trap (a
reveal that settles before the sampled window, then holds a static
frame) and the idiomatic fixes (spread the reveal / keep a blinking
caret alive) in the check reference — and pin the fingerprint's
opacity sensitivity with a regression test covering both the
visibility-floor crossing and a mid-fade value change.
* docs(catalog): regenerate code-highlight page from updated registry-item description
Only the code-highlight page is committed: a full generate-catalog-pages
run also surfaces ~34 blocks missing from the git-tracked catalog index
(pre-existing drift on main), which belongs in its own chore PR.
Running the CLI from source (tsx dev script, as CI's smoke job does)
transpiles with keepNames, which rewrites named inner functions in
serialized page closures into __name(...) calls — a helper that exists
in the Node bundle but not in the browser realm. The unified seek
closure was the first validate-path page function with named inner
functions, so 'hyperframes validate' threw '__name is not defined' in
CI while the dist build worked. Every session opener now installs a
no-op __name shim via evaluateOnNewDocument before any page script
runs, immunizing all serialized closures regardless of build mode.
Three filters keep the escalated contrast gate honest, each surfaced by
running check across the registry examples:
- data-layout-ignore (the layout audit's existing decorative opt-out)
now also excludes set-dressing text from the contrast audit — one
vocabulary for 'not copy a viewer must read'.
- Text that has (nearly) left the canvas is skipped: sampling a clamped
off-canvas box reads border pixels and produced the classic false
white-on-white (a cursor exiting the frame).
- Contrast failures follow the same persistence rule as layout findings:
observed at a single sample of a multi-sample sweep demotes to
warning; held failures gate.
Example fixes the sweep exposed: motion-blur's 21 deliberately-dim rail
labels are marked decorative (its vivid labels pass on their own);
nyt-graph's subtitle and source-note adopt the gate's suggested
compliant gray; decision-tree's declared duration drops 15s to 10s —
its content ends at ~9.5s and every render shipped a blank white tail.
The persistence-tier promotion surfaced two held content_overlap errors
on the hero heading; zooming in shows the collaborative-cursor demo
(cursor badge + typed comment bubble) hovering by design. Opt out with
data-layout-allow-overlap per the finding's own fixHint. The example's 4
pre-existing gsap_css_transform_conflict lint errors stay for a separate
example-maintenance pass.
* fix(examples): host the kinetic-type A-roll so the video actually renders
The A-roll <video> was authored inside the main-graphics sub-composition
template. The runtime only seeks and decodes media that is a direct child of
the host root, so the footage was never driven by the live runtime and renders
blank in Studio preview and the player (the producer's compile step happened to
hoist it, masking the contract violation in server renders). The example also
failed lint with eight errors.
Root cause and fixes:
- Move the <video> out of compositions/main-graphics.html and into index.html
as a direct child of #root, with data-start/data-duration/data-track-index
and class="clip". Its per-scene opacity reveal now runs on the main timeline
at global time, since a sub-composition timeline cannot reach host elements.
- Make the sub-composition a transparent overlay shell (background: transparent)
and stack it above the host video so the type renders over the footage.
- Drop the crossorigin attribute (plain displayed media never needs it) and mark
the audible footage with data-has-audio="true".
- Replace the three CSS translateY values that GSAP would overwrite with
fromTo tweens (carson-line-1, wes-text-top, wes-text-bottom).
- Swap the unbundled Libre Baskerville for the bundled Playfair Display serif so
the renderer can supply the Wes Anderson typography, and drop the redundant
-apple-system token from the body font stack.
lint reports 0 errors, validate passes, and frame extraction confirms the A-roll
composites correctly under every type scene.
* docs(examples): note the A-roll reveal-time coupling to the sub-composition
CI failures were two root causes (preview-regression was a cascade — its gate
mirrors preview-parity, which was skipped because the Preflight lint+format job
failed):
- Preflight (lint + format): the migrated registry comps (flowchart,
flowchart-vertical, liquid-glass-notification, vignette demo) were committed
unformatted — the lefthook format step only ran oxfmt on staged TS, not HTML,
so `oxfmt --check .` failed in CI. Ran oxfmt on all four. The vignette title's
per-glyph spans use oxfmt's `</span>`-split form, which keeps the glyphs
adjacent (no inter-element whitespace), so rendering is unchanged.
- Skills: manifest in sync: the pre-commit hook's manifest generator and CI's
canonical `gen-skills-manifest.ts` produced different content hashes for the
same skill; regenerated with the canonical generator so the committed manifest
matches what CI computes.

The previous fixHint and skill guidance told agents to "settle via scale" for
text-reflow props — but uniform scale resizes the glyphs, it does not change
the gaps between them, so swapping a letterSpacing tween for scale lints clean
while silently animating a different thing.
Make the guidance faithful per property:
- fontSize -> scale (same visual, sub-pixel smooth).
- letterSpacing / wordSpacing -> split the text into per-character elements and
animate each glyph's x (the spread); uniform scale is NOT equivalent. Or hold
the value statically if it's a minor flourish.
Add a "preserve the intent" principle to gsap-transforms-and-perf.md: a fix must
reproduce the same start/end state and trajectory and be verified against the
ORIGINAL render, not just pass lint — lint-clean-and-smooth is not the bar,
faithful-and-smooth is.
Redo the vignette demo title with the faithful per-glyph x spread (15.12px =
(0.32em-0.18em)*108px, centered about 8 chars). Render-verified: settled
endpoint matches the original at 46.5 dB, settle is smooth (24/24 unique frames).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Extend the rule beyond positional layout props to the text-reflow props
letterSpacing / wordSpacing / fontSize. Animating them reflows text and snaps
glyph positions to the pixel grid, so a slow ease-out tail micro-stutters
exactly like left/top — measured on a real composition, a slow letterSpacing
"settle" rendered 19/30 unique frames vs 30/30 for the transform-driven
motion in the same piece. They have no transform replacement (fix: settle via
scale or hold the value), and the snap happens during browser layout, upstream
of the canvas raster, so they are never html-in-canvas-exempt. width/height
stay excluded (legit animated uses — progress bars, reveals).
Restructure the finding's message/fixHint to compose per category (positional
-> x/y; reflow -> scale/hold; roundProps -> remove) instead of a two-branch
ternary. Skill guidance (gsap-transforms-and-perf.md) broadened: "layout
property" includes reflow; letterSpacing/fontSize named as the settle-trap.
Migrate the one surfaced positive: registry/components/vignette/demo.html
title settle letterSpacing -> a subtle scale settle (render-verified 20/20
unique frames, smooth). Blast radius across the registry was this one comp,
zero false positives.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Animating layout properties (left/right/top/bottom/margin*) or using
roundProps snaps motion to integer device pixels. Under the seek-by-frame
capture engine this is invisible at high per-frame deltas (fast tweens) but
visibly stutters at low deltas (slow tweens / ease-out tails): sub-pixel
movement rounds to the same pixel for several frames, then jumps a whole
pixel. Transforms (x/y/scale) interpolate sub-pixel and stay smooth.
New rule gsap_non_transform_motion (error):
- Sources timeline tweens from the acorn parser's full animation list, so
label- and relative-positioned tweens (tl.to(..., "label") / "+=1") are
covered and real AST keys avoid phantom-prop / nested-brace misreads.
- Exempts html-in-canvas elements (a <canvas layoutsubtree> ancestor): they
are rasterized from sub-pixel getComputedStyle and do not integer-snap.
Per-element resolution, so a grouped glass+text tween still flags the
plain-DOM half. roundProps is never exempt (it rounds before the style).
- Uses Object.hasOwn for the layout-prop lookup, skips set(), and merges
standalone gsap.* calls.
Migrated 9 registry compositions off layout-prop animation onto transforms,
each render-verified visually identical:
- liquid-glass-{notification,widgets,media-controls,context-menu}: plain-DOM
text overlays -> transforms; glass panels stay on left/top (canvas-exempt).
- vignelli: curtain wipes left:% -> xPercent.
- lt-mask-reveal: sweep left:% -> x px.
- flowchart, flowchart-vertical, decision-tree: cursor paths left/top -> x/y.

* fix(core): register sub-composition timelines after async build + lint rule
When a composition builds its GSAP timeline inside document.fonts.ready (or any
async callback), registering window.__timelines[id] BEFORE the build leaves an
EMPTY timeline registered. The runtime's sub-composition readiness gate treats
"key present" as "ready" and nests the child once — an empty timeline gets
nested empty and is never re-nested, so the frame renders blank when used as a
sub-composition.
- registry/blocks/code-{diff,highlight,morph,scroll,typing}: register the
timeline AFTER the fonts.ready build completes, then call
window.__hfForceTimelineRebind() to re-nest now that it is populated.
- core lint: add rule gsap_timeline_registered_before_async_build to flag the
early-registration anti-pattern, with tests.

* test(studio): import commitGsapPositionFromDrag from its actual module
The function was split out into gsapDragPositionCommit.ts in #1605, but the

Inherited main breakage (same fix as #1631/#1635); fixes the Test CI check on

* feat(player): slideshow fullscreen + presenter-view rework
- fullscreen toggle in the nav chrome (button + 'F' key); standard Fullscreen
API on the <hyperframes-slideshow> element, icon reflects state
- presenter console: live slide on top, speaker-notes panel below, with the nav
controls shown in-view; Present button hides once presenting (harness)
- audience (viewer) window: chrome reduced to a fullscreen-only control, no nav
- fix: audience / back() / backToMain() mirror stayed frozen on the first frame —
a bare paused seek does not repaint some compositions. resumeSlide now plays a
brief render-nudge (RENDER_NUDGE) past the target so the composition paints,
then onTime pauses at the hold
- refactor: extract reusable buildNavCluster() + wireChromeButtons(); rework
buildPresenterLayout into the bottom notes panel
- example: airbnb-deck presenter-test.html harness (Present button + 'F')
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(player): slideshow no auto-progress + presenter slide fits/pins
- navigation jumps to a static frame instead of auto-playing the timeline:
playTo() seeks to the hold (+ a brief RENDER_NUDGE to repaint) rather than
sustaining playback, so slides hold until the user advances
- presenter view: pin the live slide to the top and confine the player to the
region above the notes panel, so the player CONTAINS the composition — the
full slide stays visible (letterboxed) at any width and re-fits on resize;
its bottom is no longer cut off by the notes panel
- tests: seek targets updated for the render-nudge offset

* fix(slideshow): presenter nav flash, slide-1 boundary, branch buttons
Three presenter-mode fixes from testing the airbnb deck: (1) navigation flash — seek to the exact target then play forward to repaint, instead of seeking backward (t-0.2) which painted the previous scene at boundaries; split hold into holdTarget (logical) and holdAt (target+nudge, clamped to slide.end). (2) slide-1 boundary — no-fragment slides rest at the slide midpoint, not slide.end. (3) presenter branch buttons — surface hotspots as buttons in the presenter console (the on-slide pill is lost in the letterboxed view). Also extract paintChrome() to dedupe the three chrome-render sites.

* fix(slideshow): stop presenter nav buttons flickering / dropping clicks
The presenter elapsed clock called render() every second, which rebuilt the
entire chrome (innerHTML) including the nav buttons — they flickered and any
click landing mid-rebuild was lost. The 1s tick now updates only the elapsed
text node; the nav buttons are rebuilt only on actual navigation.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(slideshow): CSP-safe nav hover, UUID editor ids, manifest version
Addresses review feedback on the split stack:
- CSP: replace the 8 inline onmouseover/onmouseout handlers on the nav
buttons with a [data-hf-nav-cluster] button:hover CSS rule (injected once
per document). No inline event handlers → works under strict CSP.
- IDs: studio sequence/hotspot id generation used Date.now() (sub-ms
collision on rapid clicks) — now crypto.randomUUID().
- Versioning: stamp version on the persisted manifest island (preserving an
existing one); add the optional version field + SLIDESHOW_MANIFEST_VERSION
to the core schema so future schema changes can migrate older islands.
These live on the review-fixes tip (consistent with the stack's fixup-on-tip
model); the touched code belongs to ss-player-b (#1590), ss-studio-a/b
(#1591/#1592), and ss-core (#1580).

* chore(ci): fix format + fallow gates for slideshow stack
- .prettierignore: exclude generated demo compositions (registry/examples/**/*.html)
from oxfmt — large video-pipeline output (GSAP/Three/WebGL), not hand-authored
source. Was failing 'Format' repo-wide (pre-existing on main via #1584).
- .fallowrc: exempt SlideshowPanel.tsx (health/complexity — section fan-out) and
the slideshowPanelHelpers.ts / SlideshowPanel.test.ts parallel-structure clones
(duplicates.ignore). File-level config, not inline comments — inline shifts line
numbers and breaks fallow's inherited-finding fingerprint (per existing rc note).

* fix(slideshow): address PR review + CodeQL findings
- CodeQL #638 (parseSlideshow): complete the regex metachar escape in
slideshowIslandRegex (was missing backslash); add JSDoc on the factory +
lastIndex caveat (reviewer 5a/16).
- CodeQL #639/#640 + review items 13/17: remove registry/examples/airbnb-deck/
presenter-test.html — a generated test harness (postMessage w/o origin check,
proto-pollution) that was scope-creep into a fix PR and a 3rd duplicate island.
Regenerate locally via the scratchpad script when testing.
- Review item 15 (docs drift in skills/slideshow/SKILL.md): lint resolves scenes
by data-composition-id only (not .clip[id]); fragments are valid INCLUSIVE of
[start,end], not 'strictly inside'.
IIFE bundles core confirmed (0 external @hyperframes/core refs in the slideshow
global build). format/lint/fallow green.
* feat(cli): add 'present' command — serve a deck in presenter mode
hyperframes present [dir] starts a lightweight HTTP server, wraps the
composition in <hyperframes-slideshow> with its island inlined, and opens
the browser. A real HTTP origin is required for presenter mode: present()
opens the audience window via window.open(?mode=audience) and the two sync
over BroadcastChannel — neither works from file://.
- New utils/compositionServer.ts factors the server scaffolding shared with
'play' (resolve runtime/player/slideshow bundles, inject runtime, asset
content-types, bind to a free port); play.ts now uses it too.
- Errors clearly if the deck has no slideshow island.
- .fallowrc: exempt the play/present command entrypoints (validation + server
wiring) and the per-command startup/logging block from the complexity /
duplication gates.
Verified end-to-end against registry/examples/airbnb-deck: server serves the
wrapper + assets, the component binds and renders (counter 1 / 11).
* fix(cli): present renders the deck (player sizing + self-driving serve)
Two bugs caused a black slide area:
- The <hyperframes-player> had no positioning, so its iframe collapsed to
zero size — the (absolutely-positioned) chrome showed but the composition
didn't. Add position:absolute; inset:0 (matches demo.html).
- The composition was served with the engine runtime injected, which leaves
its timelines engine-paused (blank). Slideshow decks self-drive their own
timelines (like demo.html / the standalone harness), so serve them raw.
Verified end-to-end on registry/examples/airbnb-deck: cover renders, Next
advances 1/11 -> 2/11 and slide 2 paints.
* fix(cli): present plays slideshow sound effects
The composition (in the player's sandboxed iframe) posts
{ type: 'hf-sfx', name } to the parent on nav, but the iframe is
autoplay-blocked — audio must play in the parent that owns the user gesture.
Add the parent-side hf-sfx handler (the 4 standard clips advance/fragment/
branch-enter/back, served from the deck's sfx/ under /composition/sfx/),
gesture-unlocked and mute-aware, in both presenter and audience windows.
Verified: sfx serve 200 (audio/mpeg) and Next delivers [advance, fragment]
to the parent handler.
* feat(examples): softer mellow slideshow sfx for airbnb-deck
Replace the aggressive percussive pops with gentle sine-tone cues (warm
pitches C5/G4/E5/F4, 12ms attack + exponential decay, lowpassed) — advance/
fragment/branch-enter/back. Much lighter; fragment is the most subtle.
* feat(examples): whoosh + sparkle slideshow sfx for airbnb-deck
Replace the sine-tone cues with airy, designed sounds:
- advance: a soft whoosh (band-limited pink noise, bell-shaped swell)
- back: that whoosh reversed and darkened
- fragment: a light sparkle (staggered high chime blips)
- branch-enter: whoosh + a trailing sparkle (magical entry)
* feat(examples): directional whoosh + richer branch-enter cue (airbnb-deck)
- Going backward a slide now plays the reverse whoosh (back), not advance —
the sfx logic detects nav direction by scene order instead of firing advance
for every scene change.
- branch-enter is now a more interesting magical cue: a faint whoosh + an
ascending C5-E5-G5-C6 chime arpeggio + a trailing sparkle.
Verified: next then prev fires [advance, fragment, back]; no page errors.
* fix(cli): harden present sfx handler + mute-hover affordance (R2 review)
Addresses Rames R2 items 19-21:
- 20: the present audio handler reintroduced the CodeQL classes removed with
presenter-test.html — add an origin check (same-origin composition iframe)
and an own-property guard so a 'name' like __proto__ can't resolve to and
mutate Object.prototype.
- 21: assetContentType used a bare index lookup (ext='__proto__' -> prototype);
guard with Object.hasOwn.
- 19: the CSP hover rule erased the speaker button's muted color; add a
higher-specificity [data-hf-muted] [data-hf-mute]:hover override.
Verified: hf-sfx origin matches location.origin (guard passes), advance/fragment
still fire, deck renders + advances. Items 14/18/22 deferred (minor, pre-existing).
* fix(slideshow): address remaining R2 items (14/18/22) + re-remove harness
- 14: resumeSlide now mirrors enterSlide — a no-fragment slide resumes at its
midpoint (visible-at-rest), not frame-0; fragmented slides still resume to the
saved fragment or slide.start. Added a dedicated test naming the heuristic.
- 18: fullscreenchange swaps only the fullscreen glyph + aria (hoisted SVGs to
module consts) instead of re-rendering the whole chrome.
- 22: .prettierignore lists the specific generated demo compositions instead of
blanket registry/examples/**/*.html, so hand-authored example HTML still formats.
- presenter-test.html: a stray 54a4460 git add -A had re-added the deleted
harness (reviving CodeQL #639/#640); remove it again.
106 slideshow tests pass; tsc/lint/fallow/format clean; deck still renders.

Three runnable slideshow compositions: a current-Airbnb-branded remake of
the 2009 seed deck (Three.js backgrounds, GSAP entrances, hotspot branch,
HeyGen SFX), an animated startup pitch, and a minimal fixture.

* fix(lint): promote rules to errors with registry exemptions and false-positive fixes
- Export isRegistrySourceFile/isRegistryInstalledFile from composition.ts
- Add registry exemptions to google_fonts_import and font_family_without_font_face
- Add registry exemption to requestanimationframe_in_composition
- Fix timed_element_missing_clip_class: data-track-index alone no longer triggers
- Fix caption_transcript_parse_error: balanced-bracket scanner replaces non-greedy regex
- Fix missing_timeline_registry: skips sub-compositions and template-wrapped files
- Fix scene_layer_missing_visibility_kill: strip JS comments before pattern matching
- Fix gsap_css_transform_conflict: exempt from() alongside fromTo()
- Fix gsap_from_opacity_noop: only fires when opacity value is actually 0
- Add regression test for data-track-index-only elements
* test(lint): add regression tests for false-positive fixes
Covers the 7 missing negative-case assertions flagged in PR review:
- registry marker suppresses google_fonts_import + font_family_without_font_face
- registry marker suppresses requestanimationframe_in_composition
- isSubComposition suppresses missing_timeline_registry
- scene_layer_missing_visibility_kill: fires, commented-kill fires, real kill suppresses
- gsap_css_transform_conflict: from() exempt alongside fromTo()
- gsap_from_opacity_noop: non-zero opacity (e.g. 0.5) is a valid reveal, not a noop

* fix(examples): fix warm-grain template to pass promoted lint rules
- index.html: remove undeclared "Lexend" from font-family stack
- intro.html: replace Google Fonts @import with bundled Inter font
- captions.html: quote TRANSCRIPT keys for valid JSON + use Inter font
Fixes CLI smoke CI failure after google_fonts_import, font_family_without_font_face,
and caption_transcript_parse_error were promoted from warning to error.

* fix(cli): resolve warm-grain from repo registry in dev mode + bundle at build
getStaticTemplateDir now falls back to registry/examples/<id> in dev mode
so CI smoke tests use the PR-branch copy instead of fetching from main.
build-copy.mjs copies warm-grain to dist/templates/warm-grain at build time
so packed CLIs can scaffold it offline.

* fix(examples): remove trailing comma from warm-grain TRANSCRIPT array
JSON.parse rejects trailing commas (valid JS, invalid JSON).
caption_transcript_parse_error was still firing because of the comma
on the last entry after quoting all keys.

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.
* 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 morph-text preview video
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* chore(registry): fix morph-text.html formatting
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* docs(catalog): add Text Effects section and morph-text page
Moves caption-blend-difference and texture-mask-text out of Effects into a new
"Text Effects" section below it. Adds morph-text component page with install
instructions and preview video.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* 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)

Adds entries for all blocks in registry/blocks/ that were missing
from registry/registry.json:
- 12 VS Code code-snippet-* blocks (from #1113, same missed step)
- flowchart-vertical
- vfx-liquid-glass
Without these entries the CLI returns 'Item not found in registry'
even though the block files exist.
The 12 code-snippet-apple-terminal-* blocks were missing from
registry/registry.json so the CLI couldn't resolve them. Adds all
12 entries so npx hyperframes add code-snippet-apple-terminal-<theme>
and npx hyperframes add apple-terminal work correctly.
* feat(registry): add Apple Terminal theme code snippet blocks
Adds 12 Apple Terminal built-in profile visualizer blocks to the
Code Snippets catalog section, following the same pattern as the
VS Code theme blocks (commit 5245e190).
Themes: Basic, Clear Dark, Clear Light, Grass, Homebrew, Man Page,
Novel, Ocean, Pro, Red Sands, Silver Aerogel, Solid Colors.
Each block is a self-contained 1920×1080 composition showing a
macOS Terminal.app window in the matching profile colors, with
per-character GSAP typing animation and window.__timelines contract.
Install individually:
npx hyperframes add code-snippet-apple-terminal-basic
Install all Apple Terminal themes:
npx hyperframes add apple-terminal

* fix(registry): remove placeholder preview URLs for unrendered Apple Terminal themes
The 8 themes without rendered videos (clear-dark, homebrew, novel,
ocean, pro, red-sands, silver-aerogel, solid-colors) had preview.video
URLs pointing to non-existent S3 objects, returning 403. Removed the
preview field from their registry-item.json and the video embed from
their MDX pages until renders are available.
The 4 themes with uploaded videos (basic, clear-light, grass, man-page)
retain their preview URLs and are live on CDN.
* fix(registry): add apple-terminal tag so npx hyperframes add apple-terminal works
* feat(registry): render + upload all 12 Apple Terminal preview videos to CDN
Rendered the 8 missing themes (clear-dark, homebrew, novel, ocean, pro,
red-sands, silver-aerogel, solid-colors) using npx hyperframes@latest
render and uploaded to the hyperframes CDN. All 12 themes now have
live preview.video URLs and video embeds in their MDX pages.
All 12 CDN URLs return 200.
* style: format Apple Terminal HTML and JSON files with oxfmt

* feat(registry): add VS Code theme visualizer example
Full VS Code workbench recreation with per-character typing animation
across 12 built-in themes. Includes activity bar, sidebar, tabs,
editor with line-by-line cursor tracking, terminal panel, and status
bar — all driven by official VS Code theme JSON files.
Themes: Dark Modern, Dark 2026, Dark+, Light Modern, Light 2026,
Light+, Visual Studio Dark, Visual Studio Light, High Contrast,
High Contrast Light, Solarized Light, Monokai.
Includes build scripts to regenerate compositions from theme JSON.
* feat(registry): add 12 code snippet blocks for hyperframes add code
Individual blocks for each VS Code built-in theme, all tagged "code"
so `npx hyperframes add code` installs the full set.
Each block is a self-contained VS Code workbench with per-character
typing animation, activity bar, sidebar, tabs, terminal, and status
bar driven by official theme JSON data.
* docs: add mdx pages for code snippet blocks and example
- 12 block doc pages under catalog/blocks/code-snippet-*
- "Code Snippets" nav group in docs.json
- vscode-theme-visualizer entry in examples.mdx
* docs: revert examples.mdx — code snippets belong in catalog only
* docs: drop redundant 'Code Snippet' prefix from sidebar titles
* docs: add video previews to code snippet catalog pages
* style: format HTML, CSS, and MJS files for CI
* fix: address review feedback — build pipeline, LICENSE, dead code, nav order
1. Build script now regenerates both example compositions AND published
blocks in registry/blocks/code-snippet-*/, keeping them in sync.
2. Add MIT LICENSE for vendored VS Code theme JSONs (microsoft/vscode).
3. Remove dead `chars` variable from runtime, build script, all blocks,
and all example compositions.
4. Alphabetize Code Snippets nav group in docs.json to match catalog
convention.
* style: format all build-generated files (render-entries, CSS, index)
