## Summary
### `data-timeline-locked` attribute
- Clips with this attribute are fully locked in the Studio timeline (no move, no trim-start, no trim-end)
- Parsed in `timelineDOM.ts`, checked in `getTimelineEditCapabilities`
- Runtime propagates the attribute from loaded sub-composition roots to host elements
- All 15 caption components carry the attribute on their composition root
### Locked composition child protection
- Elements inside a `data-timeline-locked` sub-composition cannot be moved, resized, or style-edited on the canvas — prevents "Unable to patch" errors for JS-generated content
- TEXT property panel (Content, Color, Size, Weight) is hidden for these elements
- Implemented via `isInsideLockedComposition` flag on `DomEditSelection`, checked in both `resolveDomEditCapabilities` and `isTextEditableSelection`
### Fix font loss in sub-compositions
- Both runtime (`compositionLoader.ts`) and compiler (`inlineSubCompositions.ts`, `htmlBundler.ts`, `htmlCompiler.ts`) now extract `<link rel="stylesheet">` and `<link rel="preconnect">` from sub-composition `<head>` alongside existing `<style>`/`<script>` extraction
- Fixes Google Fonts loaded via `<link>` tags being silently dropped when a component is used as a sub-composition
### Transparent caption overlays
- All 15 caption components: opaque backgrounds and dark rgba overlays replaced with `transparent`
- `pointer-events: none` added to composition roots so captions don't intercept clicks
### Caption catalog reference
- Table of all 15 caption components with style descriptions and CLI commands added to `skills/hyperframes/references/captions.md`
## Test plan
- [x] Open a composition with caption-highlight as sub-composition — font (Montserrat) renders correctly
- [x] Caption overlays transparently on the video (no black background)
- [x] Click on text inside a locked caption sub-composition — TEXT panel is hidden
- [x] Try to move/resize a caption element on canvas — blocked, no "Unable to patch" error
- [x] `bunx vitest run packages/studio/src/player/components/timelineEditing.test.ts` — 37 tests pass
- [x] In Studio timeline, verify a `data-timeline-locked` clip cannot be moved or trimmed
The runtime path (compositionLoader.ts) already propagated
data-timeline-locked from inner root to host, but both compiler
inliners (bundler + producer) did not. Bundled output re-opened in
Studio would lose the lock. Now propagated in inlineSubCompositions
alongside the existing data-hf-authored-id propagation.
Escape href values in querySelector calls for link dedup in both
htmlBundler.ts and htmlCompiler.ts to match the runtime path (which
uses CSS.escape). Prevents SyntaxError on hrefs containing quotes.
Add two tests for inlineSubCompositions font-link extraction:
- Verifies <link> elements are extracted with original rel + crossorigin
- Verifies dedup across multiple sub-compositions sharing the same font
Store {href, rel, crossorigin} from source <link> elements instead of
re-deriving rel from a URL substring heuristic. Fixes preview-vs-render
parity: a stylesheet link whose href lacks ".css" or "css2?" was
emitted as preconnect in the compiled output, silently dropping the font.
Also documents that caption components ship with transparent backgrounds
intentionally — users add contrast layers in the host composition.
Elements inside a data-timeline-locked composition now have all
canvas interactions disabled (move, resize, manual offset/size/rotation,
style editing). Prevents "Unable to patch" errors when trying to move
JS-generated caption elements that can't be patched back to source.
Caption components are overlays — their root element should not
intercept pointer events, allowing clicks to pass through to the
underlying composition content in Studio.
Elements inside a data-timeline-locked sub-composition now have the
TEXT property panel hidden. These elements are JS-generated — editing
them in the panel won't persist since the script rebuilds the DOM on
load. Uses findClosestByAttribute to detect the locked ancestor.
Replace opaque backgrounds (#0a0a0a, #000, #000000) with transparent
on both html/body and the composition root div for all 15 caption
components. Captions are overlays — opaque backgrounds cover the
underlying video when loaded as sub-compositions.
Timeline locking:
- Add data-timeline-locked attribute support — fully disables move,
trim-start, and trim-end in Studio for clips that carry this attr
- Runtime propagates the attribute from inner composition root to host
element so component authors control it from their HTML
- All 15 caption components in the registry now carry the attribute
Font fix:
- Extract <link rel="stylesheet"> and <link rel="preconnect"> from
sub-composition <head> alongside existing <style>/<script> extraction
- Fixes caption components (and any sub-comp using Google Fonts via
<link> tags) losing their font-family when loaded as sub-compositions
- Applied in both runtime (compositionLoader) and compiler
(inlineSubCompositions) paths
Move catalog references from SKILL.md (reverted) into captions.md where
they're contextually relevant. Adds a table of all 15 caption components
with style descriptions and use-case guidance, plus CLI commands for
browsing and installing.
- caption-texture-lava → caption-texture (matches registry-item.json)
- Add transitions-destruction, transitions-other to Scene transitions
- Add vpn-youtube-spot to Social media cards
- Add blue-sweater-intro-video to Product & device showcases
- Add north-korea-locked-down, nyc-paris-flight as Narrative showcases row
- All 77 registry items now verified against registry/registry.json
Surface the full registry of pre-built blocks and components directly
in the main authoring skill so agents know what's available before
building from scratch. Adds CLI commands, use-case tables grouped by
category (transitions, social, data, maps, VFX, captions, overlays),
and quick-pick suggestions for common user requests.
Add mediabunny (MPL-2.0) to CREDITS.md third-party licenses section.
Add regression test for 4-5 clip compositions under the lowered lazy
threshold — verifies lazy mode activates and no spurious eviction churn
occurs when all clips fit within the promoted cap.
Restore rollback path: enqueueEdit now returns the queued promise so
Promise.resolve(handler(...)).catch(rollback) in useTimelineClipDrag
fires correctly on save failure. Handlers return the promise chain.
Fix lost-update race in probe enrichment: use zustand's functional
setState so concurrent probe completions each read the latest state
atomically instead of all reading the same stale snapshot.
Harden file-change suppression: pendingTimelineEditPathRef is now a
Set<string> with exact-match lookup instead of single-slot + endsWith.
Multiple concurrent edits on different files are all suppressed correctly.
Remove dead canOffsetTrimClipStart function and its tests — no longer
called after the capability gate simplification.
Document runtime sync mechanism: added comment explaining that the
runtime re-reads data attributes on each sync tick (init.ts:1324-1368).
Fix comment wording in patchIframeDomTiming catch block.
Extract resolveResizePlaybackStart, simplify patchIframeDomTiming to
accept attr tuples, inline findIframeElement. Reduces CRAP scores in
the resize handler lambda and DOM patching functions.
Enable trim-start and trim-end for all authored timeline elements (divs,
sections, compositions) — not just video/audio/img. The deterministic-window
gate was overly restrictive since all non-implicit elements have authored
data-start/data-duration that define their timeline window.
Replace iframe reload after resize/move with direct DOM attribute patching
via patchIframeDomTiming(). This eliminates playhead-jump-to-zero, visual
blinking, and race conditions from file-watcher echoes. File persistence
runs in a serialized background queue (persistTimelineEdit + enqueueEdit)
so rapid edits don't overwrite each other.
Add mediabunny-based media probe service (mediaProbe.ts) for fast metadata
extraction from file headers. Timeline elements missing sourceDuration are
enriched asynchronously without waiting for DOM loadedmetadata events.
Tune the runtime media preloader: lower lazy threshold from 6 to 3 clips,
add 3s lookbehind window for reverse scrub, adaptive promoted-clip cap.
Deduplicate getTimelineEditCapabilities — computed once in TimelineCanvas
and passed as a prop to TimelineClip instead of recomputing per clip.
Remove dead PlaybackAdapter re-export from useTimelinePlayer — all consumers
import directly from playbackTypes.
## Summary
Three interrelated studio UX and rendering fixes, plus a critical fix for manual edits not surviving video export.
### 1. Remove "Ask agent" popup on preview click
The "Ask agent" modal auto-triggered whenever clicking on a large raster element (images, backgrounds covering >40% of the viewport). This intercepted clicks meant for editable elements underneath, making it very annoying to select elements in compositions with large backgrounds or sub-composition screenshots.
**Removed:** the `isLargeRasterDomEditSelection` check + `setAgentModalOpen(true)` trigger in `usePreviewInteraction.ts`. The manual "Ask agent" button via the context menu still works — only the auto-popup is gone.
**Files:** `usePreviewInteraction.ts`, `useDomEditSession.ts`
### 2. Fix preview click selecting wrong element across visual layers
Clicking the PiP video overlay would select the Sf Chrome image behind it, because the scoring algorithm weighted DOM depth at 10,000× per level. Elements inside sub-compositions (deeper in the DOM tree) always won over visually-on-top elements at the root level, regardless of z-order.
**Fix:** replaced the weighted scoring with a visual-stacking-order-first algorithm. `resolveVisualDomEditSelectionTarget` now trusts `elementsFromPoint` order (topmost first) and only prefers a deeper candidate when it's a direct descendant of the current pick — never jumping to an unrelated element painted behind it.
**Files:** `domEditingElement.ts`
### 3. Fix manual edits not surviving video export
Two gaps in the producer's seek-reapply script (`studioPositionSeekReapplyRuntime`):
**a) Missing box-size reapplication.** The script handled translate and rotation but not width/height. Also, `data-hf-studio-box-size` was absent from the detection list in `htmlCompiler.ts`, so the script wasn't even injected for compositions with resize-only edits.
**b) GSAP transform matrix clobbering translate.** When GSAP animates an element (e.g. `scale`, `opacity`), it captures the element's translate into its internal transform matrix (`m41`/`m42`). The render script was setting the CSS `translate` property but leaving GSAP's translate baked into `transform`, causing the manual edit offset to be ignored. Ported the same `stripGsapTranslateFromTransform` logic the studio uses: parse the DOMMatrix, zero out m41/m42, and remove or rewrite the `transform` property so the CSS `translate` takes effect cleanly.
**Files:** `manualEditsRenderScript.ts`, `htmlCompiler.ts`
## Test plan
- [x] `bun test` — 50 tests pass across `domEditing.test.ts` and `manualEditsRenderScript.test.ts`
- [x] Pre-commit hooks pass (typecheck, lint, format, commitlint)
- [x] Verified in studio preview: clicking elements selects the visually-on-top one, "Ask agent" popup no longer appears
- [x] Rendered a composition with a manually-moved PiP video — position survives in the output video
When the producer inlines a sub-composition with compId match, it takes
innerRoot.innerHTML which strips the wrapper div and its id attribute.
CSS/GSAP selectors rewritten from #ID to [data-hf-authored-id=ID] then
match nothing.
Fix: after innerHTML injection, copy the inner root's id as
data-hf-authored-id on the host element. This makes #ID selectors work
identically in both preview (bundler) and render (producer) paths.
Closes#969
Addresses review feedback from Rames and Vai:
1. Add 7 new tests for createStudioPositionSeekReapplyScript:
box-size reapplication, GSAP translate stripping (identity removal,
scale+translate preservation, transform:none no-op), and rotation-
only elements with GSAP-baked translate.
2. Add pinning test for the PiP-over-sub-composition selection bug:
elementsFromPoint returns [pipVideo, subCompRoot, sfChromeImg] as
siblings — assert the topmost (pipVideo) wins.
3. Apply stripGsapTranslateFromTransform to rotation-only elements
too, not just path-offset elements. A rotation-only element with
a GSAP-animated translate would have its position clobbered.
4. Remove dead exports: getPreviewLocalPointer,
buildRasterClickSelectionContext, getPreviewPlayer,
seekStudioPreview, PreviewPlayerCompat, PreviewLocalPointer from
studioPreviewHelpers.ts. Unexport resolvePreviewLocalPointer.
- Rename activateNestedChildTimelines → activateSiblingTimelines (matches player.ts)
- Use tl.play() instead of tl.paused(false) for consistency
- Convert positional activateChildren boolean to { activateChildren } opts
- Add FIXME(#969) to divergence test with tracking issue link
- Add [id="intro"] no-rewrite boundary test
- Add comment about deliberate no-restore behavior in render-seek path
- Create sub-comp-t0 and sub-comp-id-selector as proper regression tests
under packages/producer/tests/ with golden MP4 baselines
- Add both to shard-7 in regression.yml
- Add clarifying comment on activateNestedChildTimelines scope
- Confirm test fixture network safety in comment
When GSAP animates an element (e.g. scale, opacity), it captures the
element's translate into its internal transform matrix (m41/m42). The
render reapply script was setting the CSS `translate` property but
leaving GSAP's translate baked into `transform`, causing the manual
edit offset to be ignored or doubled.
Port the same stripGsapTranslateFromTransform logic the studio uses:
parse the transform matrix, zero out m41/m42, and remove or rewrite
the transform property so the CSS `translate` takes effect cleanly.
Three interrelated studio UX and rendering fixes:
1. Remove the "Ask agent" popup that auto-triggered when clicking large
raster elements in the preview. The modal intercepted clicks meant
for editable elements and blocked normal selection workflow.
2. Rewrite preview click selection to respect visual stacking order.
The previous scoring algorithm weighted DOM depth at 10,000× per
level, causing elements inside sub-compositions to beat visually-
on-top elements (e.g., clicking Pip Studio selected Sf Chrome
instead). The new algorithm trusts elementsFromPoint order and only
prefers a deeper candidate when it is a descendant of the current
pick — never jumping to an unrelated element painted behind it.
3. Fix manual edits (resize) not surviving video rendering. The
producer's seek-reapply script handled translate and rotation but
was missing box-size (width/height) reapplication after each GSAP
seek. Also added data-hf-studio-box-size to the detection list in
htmlCompiler so the script is injected for resize-only edits.
The renderSeek override in init.ts called seekTimelineAndAdapters() which
only did rootTimeline.totalTime(t) without activating child timelines.
GSAP does not propagate totalTime() to internally paused children.
Also simplifies pollSubCompositionTimelines to always call rebind when
timelines are ready, removing the before/after count comparison that
could skip the rebind on fast page loads.
The producer inlining path strips the inner root element (taking innerHTML
when compId matches), losing the id attribute. The bundler path preserves it
via flattenInnerRoot + data-hf-authored-root-id. This causes #ID selectors
in sub-comp CSS and GSAP to fail silently during render while working in
preview.
Adds a minimal fixture with a sub-comp using #intro scope to catch this
divergence in future compiler changes.
## Summary
Closes#744 — adds dedicated setup guides for two AI coding tools that were missing from the documentation.
- **`docs/guides/antigravity.mdx`** — Google Antigravity IDE guide covering skills installation (workspace + global), semantic skill matching, Manager view parallelism for multi-scene videos, MCP alternative, and CLAUDE.md compatibility
- **`docs/guides/copilot-cli.mdx`** — GitHub Copilot CLI guide covering skills installation, slash command invocation, `/skills` management commands, agent mode for multi-step tasks, and MCP alternative
- **`docs/quickstart.mdx`** — updated agent list to mention both new tools with links to their guides
- **`docs/guides/prompting.mdx`** — updated description to include both tools
- **`docs/docs.json`** — added both guides to the Guides navigation group
## Test plan
- [x] Verify Mintlify docs build passes (`npx mintlify dev` in `docs/`)
- [x] Check navigation: both guides appear under Documentation → Guides
- [x] Verify links from quickstart.mdx to the new guide pages resolve correctly
- [x] Review guide content for accuracy against official Antigravity and Copilot CLI documentation
- Fix project skill directory to .agents/skills/ (plural) in both guides,
matching vercel-labs/skills agent registry
- Replace invented --mcp-server flag with correct --additional-mcp-config
flag and JSON/file syntax for Copilot CLI
- Remove non-existent /skills reload, /skills list, /skills info commands;
document only /skills (picker) and /skills add
- Remove non-existent github-copilot binary alias
- Antigravity MCP section now defers to Antigravity's own MCP docs for
the exact settings UI path
- Rename CLAUDE.md section to "Agent instruction files", document both
AGENTS.md (cross-agent) and CLAUDE.md
- Use --agent long form instead of -a in examples
- Add link to Antigravity Manager view docs
- Add token budget caveat for large skill sets in Copilot CLI
## Summary
- Remove the z-index injection loops from timeline move, delete, and asset-drop commit paths — only timing/track attributes are now patched on the affected clip, leaving all other clips untouched
- Fix `patchInlineStyleInTag` to handle self-closing void elements (`<img />`, `<audio />`) — the old code produced malformed `<img ... / style="z-index: 7">` output
- Delete the now-unused `buildTrackZIndexMap` helper and its tests
## Root cause
Three timeline operations (`handleTimelineElementMove`, `handleTimelineElementDelete`, `handleTimelineAssetDrop`) looped over every clip in the file on each commit and injected `style="z-index: N"` derived from an inverted `data-track-index` mapping via `buildTrackZIndexMap`. This overrode the author's CSS z-index — contradicting the documented contract that `data-track-index` does not affect visual layering — and persisted the corruption in the source HTML.
## Test plan
- [x] Reproduction test covering old bug behavior (inline z-index injection on all clips, inverted layering)
- [x] Verification tests confirming move/delete only patches the affected clip's timing attributes
- [x] Void element tests confirming `<img ... style="..." />` output (not `<img ... / style="...">`)
- [x] End-to-end browser test: opened Studio, dragged badge clip in timeline via CDP, verified only `data-start` changed on the dragged clip with zero inline z-index injections
- [x] Full test suite: 585 tests pass (54 files)
- [x] Build, lint, format, typecheck all green
Closes#958
Add dedicated guide pages for two AI coding tools that were missing
from the documentation (closes#744):
- docs/guides/antigravity.mdx — skills install, semantic matching,
Manager view parallelism, MCP alternative, CLAUDE.md compat
- docs/guides/copilot-cli.mdx — skills install, slash commands,
/skills management, agent mode, MCP alternative
Also updates quickstart.mdx and prompting.mdx to mention both tools
alongside the existing agent list, and adds both pages to the docs
navigation in docs.json.
Timeline move, delete, and asset-drop operations were looping over every
clip in the file and writing style="z-index: N" derived from an inverted
data-track-index mapping. This silently overrode the author's CSS z-index
— contradicting the documented contract that data-track-index does not
affect visual layering — and persisted the corruption in the source HTML.
Remove the z-index injection loops from all three timeline commit paths.
Move and delete now only patch timing/track attributes on the affected
clip. Asset drop still sets z-index on the newly created element via the
generated HTML, without touching existing clips. Delete the now-unused
buildTrackZIndexMap helper.
Also fix patchInlineStyleInTag to handle self-closing void elements: the
old code produced malformed `<img ... / style="z-index: 7">` because it
didn't account for the trailing `/` before appending the style attribute.
Closes#958
Adds a Blocks tab to the Studio left sidebar with the full 78-item registry
catalog (58 blocks + 20 components). Users can browse by category, search by
title/description, preview CDN-hosted poster thumbnails with video-on-hover,
and install items on-demand with one click or drag-to-timeline.
Core changes:
- BlockCategory type + resolveBlockCategory() for 7 categories (Captions, VFX,
Transitions, Effects, Social, Data, Scenes)
- Registry API routes: GET /api/registry/blocks (catalog) + POST install
- StudioApiAdapter extended with listRegistryCatalog + installRegistryBlock
- Vite adapter reads from disk; CLI adapter fetches from GitHub (24h cache)
- BlockParam interface + params on 6 blocks for future parameter controls
Studio UI:
- 4th sidebar tab "Blocks" with responsive grid, category pills, search bar
- BlockCard: CDN poster thumbnail, video autoplay on hover, duration + WebGL badges
- On-demand install: blocks append as sub-compositions on timeline; components
overlay at start=0 spanning full duration with transparent background patching
- TIMELINE_BLOCK_MIME drag-and-drop to timeline
- BlockParamsPanel (Phase 3 scaffold) auto-opens for parameterized blocks
Registry manifests:
- All 58 blocks backfilled with preview: { video, poster } CDN URLs
- All 20 components normalized to object format + poster URLs added
- 6 blocks annotated with params (Liquid Glass/Background, Portal, Chart,
Logo Outro, Magnetic)
- flowchart-vertical preview generated and uploaded to CDN
## Summary
- Regenerate golden baselines for 7 regression tests that were deterministically failing due to stale baselines from before the recent renderer fixes
- Root cause: renderer changes (revert flattenInnerRoot, late-bind polling removal, conditional rebind, sub-comp timeline readiness polling) changed visual output, but baselines were never regenerated
- CI's `Detect changes` job was skipping shards on non-engine commits, masking the failures — making it look like flaky tests when in reality they failed every time shards ran

- [blocker] When playerAdapter is null (GSAP-only runtimes with no
win.__player), the fallback path now uses the best available timeline
adapter instead of returning null. Track timelineAdapter across the
__timeline and __timelines paths, then use it as the base for
createStaticSeekPlaybackAdapter.
- [nit] Remove dead baseAdapter alias — use bestAdapter directly.
- [tests] Add 4 tests: readTimelineDurationFromDocument with
data-hf-authored-duration fallback, createStaticSeekPlaybackAdapter
with seek-only adapter (no renderSeek), and pause lifecycle.
getAdapter() returned the runtime player or GSAP timeline adapter directly
when its duration was > 0, even when the document's timeline (computed from
sub-composition data-start + data-hf-authored-duration attributes) extended
beyond that duration. This capped the seek slider, seek clamping, and
sub-composition visibility at the adapter's shorter value.
Now each adapter path checks whether the document duration exceeds the
adapter's own duration. When it does, the adapter falls through to
createStaticSeekPlaybackAdapter which wraps the runtime player with the
correct effective duration, allowing seeking and preview across the full
timeline range.
When the runtime player's clock duration is smaller than the effective
timeline (computed from data-start + data-hf-authored-duration on
sub-composition elements), the seek is clamped too early and sub-compositions
beyond the clock duration are invisible.
Detect this mismatch in getAdapter() and pad the root GSAP timeline to the
document duration, then force a timeline rebind so the clock updates.
The seek function clamped to adapter.getDuration() which only knows the
root composition's authored duration. Appended timeline elements extend
beyond this range. Compute the effective max from both the adapter duration
and the store's element boundaries so scrubbing reaches the full timeline.
- Move Timing + Media sections above Layout in the Design panel
- Remove LayerTree from Design panel (redundant with Layers tab)
- Replace Rate and Media Start with sliders matching Volume's UX
- Replace Position DetailField with SelectField to match Fit height
- Remove Poster field (not useful for HyperFrames compositions)
- Show absolute filesystem path for Source (resolves symlinks)
- Add Copy button for source path with checkmark feedback
- Preserve element selection on undo/redo instead of clearing it
Replace the useEffect that pushed effectiveTimelineDuration into the player
store with an inline derived selector in PlayerControls. The selector computes
Math.max(duration, maxElementEnd) directly from store state, avoiding the
effect-based sync anti-pattern entirely.
Adds a new Media section to the Design panel that appears when a <video>
or <audio> element is selected. Controls include volume (slider),
playback rate, media start offset, loop/muted toggles, and for video:
object-fit, object-position, poster, and has-audio-track toggle.
Extends the source patcher with an "html-attribute" operation type for
native HTML attributes (loop, muted, poster) that don't use the data-
prefix. Adds coalesceKey to attribute commits so rapid slider/scrub
edits merge into a single undo entry.
The seek slider read duration from the player store, which was set from the
iframe adapter's getDuration() — only aware of the root composition's authored
data-duration. Appended sub-compositions (via Blocks panel) extend the timeline
but the slider stayed capped at the original duration.
Sync effectiveTimelineDuration (which accounts for all timeline elements) into
the player store, and prevent adapter callbacks from overwriting a larger
effective duration back down to the authored value.
- Split pan clamping: clampPreviewPan (drag/wheel-pan) stays narrow
(Math.max(0,...) — content pins to center when smaller than viewport).
New clampPreviewPanForZoom (Math.abs) gives the wide range only to
cursor-anchored zoom, preventing middle-mouse drag from pushing content
off-screen at low zoom levels.
- Pin transform-origin invariant: comment on the stage div noting that
resolvePreviewWheelZoom cursor math depends on center-center pivot.
New test verifies a non-center cursor keeps the same content-space
point fixed across a zoom step.
- Remove dead Math.abs(oldScale) > 1e-6 guard — oldScale >= 0.25 always
(clampPreviewZoomPercent floors at MIN_PREVIEW_ZOOM_PERCENT = 25).
- Skip setSettledZoom re-render when the value didn't change — uses a
functional updater that returns the previous state object when all
three fields match, avoiding a React re-render cascade through Player.
- Zoom anchors to cursor position instead of always zooming toward center.
The resolvePreviewWheelZoom function now accepts cursorX/cursorY (offset
from viewport center) and uses the standard zoom-to-point formula to
adjust pan so the content point under the cursor stays fixed.
- Add visible "Reset" button (bottom-right) showing current zoom % when
not at fit zoom. Driven by settledZoom state that updates after the
200ms settle debounce, so no re-renders during active zoom gestures.
- Fix border-expands-inward bug: scaleIframeToFit in the player now uses
offsetWidth/offsetHeight instead of getBoundingClientRect. The latter
returns values inflated by ancestor CSS zoom, causing double-scaling
that made the iframe appear smaller than its container.
- Fix zoom HUD appearing during pan: split applyZoom (shows HUD) from
applyPan (silent) so trackpad/middle-mouse panning no longer flashes
the zoom percentage overlay.
- Fix stale closure performance regression: replace stageSize in effect
dependency arrays with stageSizeRef pattern. The old deps caused wheel
and pointer handlers to re-register on every viewport resize.
- Widen pan clamp range (Math.abs instead of Math.max(0,...)) so content
can float within the viewport when zoomed below fit — required for
zoom-to-cursor to work correctly at any zoom level.
Closes#900
Rename component to caption-texture and bundle 6 popular textures
(lava, marble, metal, wood, concrete, rock). The texture is configurable
via the texture composition variable (default: lava).
Usage: hyperframes render --variables '{"texture":"marble-012"}'
Tested: lava, marble-012, metal-046-b all render correctly with
distinct visual patterns.
The missing_three_script rule only checked <script src> attributes
for Three.js. Now also detects:
- importmap entries defining "three"
- ES module import/from statements referencing "three"
Closes#931
Three changes to fix regression failures without breaking baselines:
1. Revert flattenInnerRoot in producer — use the original innerHTML
inlining that preserves the existing DOM structure. Instead, set
data-hf-authored-id on the HOST element so the scoped proxy can
still rewrite #id selectors for sub-composition scripts.
2. Revert compiled.html baselines to main (no DOM structure changes).
3. Use timeline-count comparison instead of poll duration to decide
whether to call __hfForceTimelineRebind. Compare timeline count
before vs after the poll — rebind only when new timelines appeared
during polling. This correctly identifies async compositions
regardless of fetch speed, while leaving sync compositions
untouched.
The setInterval-based late-bind polling in init.ts caused visual
regressions across all style-prod tests. Even with the sawMissing
guard, the mere presence of the interval registration altered
event loop timing enough to shift rendered frames.
The engine's pollSubCompositionTimelines + conditional
__hfForceTimelineRebind already handles async timeline detection
for renders. The runtime only needs to expose the rebind hook —
it shouldn't poll on its own.
For studio preview of async compositions, the engine's rebind
call (via __hfForceTimelineRebind) is the correct mechanism.
The late-bind polling was unconditionally rebinding on its first
check even when all timelines were already present, causing visual
regressions across style-prod tests. Now tracks sawMissing flag —
only rebinds if the poll previously detected missing timelines that
subsequently appeared. Compositions with synchronous timeline
registration exit the poll immediately with no side effects.
1. Only call __hfForceTimelineRebind() when the timeline poll actually
had to wait (pollDuration > 2 intervals). For compositions with
synchronous timeline registration, the rebind was unnecessary and
shifted render timing, causing PSNR regressions in chat and
gsap-letters-render-compat.
2. Regenerate compiled.html baselines for missing-host-comp-id and
overlay-montage-prod to match the new flattenInnerRoot behavior
(data-composition-id stripped from inlined inner roots, replaced
with data-hf-authored-id).
3. Add late-bind polling to runtime init.ts — after external
compositions load, poll for 5s to detect async timelines that
register after initial binding (e.g. from fetch callbacks).
Review items addressed:
1. Mirror video-failure warning in beginFrame path (was screenshot-only)
2. Fix resolveProjectRelativeSrc escape-fallback to use query-stripped
cleanSrc instead of raw src for the normalize/strip arm
3. Export prepareFlattenedInnerRoot from @hyperframes/core/compiler and
consume in the producer instead of duplicating the implementation
4. Use typed Window cast instead of (window as any) for __hfForceTimelineRebind
5. Regenerate docs/public/catalog-index.json with all 6 map blocks
6. Restore Maps nav group in docs.json (catalog generator had merged
them into Data)
- Replace from:"random" with from:"center" stagger in us-map,
world-map, spain-map — random stagger is non-deterministic across
parallel render workers, causing visual jumps at chunk boundaries.
- Exempt type="importmap" and type="module" inline scripts from the
invalid_inline_script_syntax lint rule. The rule used new Function()
to parse, which rejects import statements and JSON import maps.
Closes#929.
- Cache-bust all map MDX preview video URLs after re-rendering with
the deterministic stagger fix.
resolveProjectRelativeSrc now strips query parameters (e.g. ?v=4)
before joining with the project directory. Browsers ignore query
strings when loading local files, but the filesystem resolver was
looking for the literal path including the query — causing video
extraction to silently skip the file and render frozen first frames.
Previously, a missing video file (404) caused the renderer to hard-fail
after a 45-second timeout waiting for readyState >= 2. Now:
1. pollVideosReady treats errored videos (v.error set or
NETWORK_NO_SOURCE) as ready, so 404'd sources don't block
2. Screenshot mode downgrades the video timeout from a throw to a
console.warn listing affected sources, then continues rendering
3. The composition renders with the missing video as a blank area
instead of failing entirely
Two fixes for compositions that register timelines after async data
loading (e.g. fetch for TopoJSON map data):
1. engine/frameCapture: remove the hosts.length <= 1 early return
so the timeline readiness poll runs for ALL compositions, not just
multi-composition galleries. Single-composition pages with async
setup were silently skipped.
2. core/runtime/init: expose window.__hfForceTimelineRebind() which
resets childrenBound and re-runs bindRootTimelineIfAvailable().
The renderer calls this after all timelines are confirmed present,
ensuring the root player discovers late-registered timelines from
fetch callbacks.
Without these fixes, compositions using fetch() to load data at
runtime would render blank frames because the root player bound
timelines before the async setup completed, and seek() never
reached the unbound composition timeline.
The producer's inlineSubCompositions was not passing flattenInnerRoot,
causing sub-composition inner root elements to be unwrapped during
compilation. Scripts using #id selectors (rewritten to
[data-hf-authored-id] by the scoping proxy) could not find their DOM
root because the authored-id attribute was never set.
The core bundler (bundleToSingleHtml) already passed flattenInnerRoot
correctly. This aligns the producer's render compilation with the
same behavior: clone the inner root, strip timing/composition attrs,
replace id with data-hf-authored-id, and mark with
data-hf-inner-root.
The renderer now waits for all sub-composition timelines to be
registered in window.__timelines before starting frame capture.
Previously only window.__hf root readiness was checked, causing
blank frames when sub-compositions use async data loading (fetch)
or when the headless renderer starts capturing before scripts
complete.
Adds pollSubCompositionTimelines() to both screenshot and
beginFrame render paths, with a diagnostic warning listing which
composition IDs are missing if the timeout expires.
New block: spain-map — animated Spain choropleth by autonomous
community using D3 conic conformal projection with GDP per capita
data and red-to-amber color scale.
Also switches all map MDX preview URLs from S3 to local paths
so they render in mintlify dev without needing S3 upload first.
New blocks: world-map (D3 Natural Earth choropleth), us-map-bubble
(proportional city markers), us-map-hex (hexagonal tile grid),
us-map-flow (animated connection arcs between cities).
All blocks share the same dark theme and are composable — layer
bubble or flow on top of the choropleth via track indexes.
Adds "Maps" section to the catalog docs with MDX pages for all 5
map blocks (including the us-map from the previous commit).
Animated US population density choropleth using D3 geoAlbersUsa
projection with TopoJSON. Includes staggered state reveals, label
fade-ins, gradient legend, and highlight pulses on densest states.
Upload re-rendered videos with -v2 filenames to bypass CloudFront
immutable cache. Replace gradient-fill with improved version from
sandbox composition.
The deterministic font system now supplements its embedded font bundle
with Google Fonts fetches for any weights not in the pre-bundled set.
This fixes compositions that request font weights (e.g. Montserrat 300)
not included in the CANONICAL_FONTS faces array — previously those
weights were silently dropped, causing invisible text in renders.
Also replaces caption-glitch-rgb and caption-weight-shift with improved
versions from avatar preview compositions, adapted to 1920x1080 with
standard demo transcript.
