* fix(cli): the Windows Chrome check launches Chrome instead of trusting chrome.exe --version
* refactor(cli): shorten the Windows Chrome version comment to fit the comment ratchet
* test(cli): pin the platform in the Unix Chrome preflight tests so Windows runs them as written
* fix(cli): the Windows Chrome check reads the file version, not chrome.exe --version
* fix(cli): Windows preview and catch-up records move to LOCALAPPDATA, a refused log no longer blocks
* fix(cli): a refused preview log falls back to the null device and drops the extra comments
* fix(cli): Windows catch-up record goes under LOCALAPPDATA/hyperframes like the other records
* fix(cli): the check and snapshot project lock works where hard links are refused
* refactor(cli): drop the project lock comment to fit the comment ratchet
* fix(render): a PNG's colour tags no longer change its pixels in preview, check, snapshot or render
* fix(render): the play and present server also serves a PNG without its colour tags
* fix(render): bundled pages inline a PNG without its colour tags too
* feat(core): one function gives the media time that shows the frame starting at an instant
* fix(core): paused preview and render show the same, correct video frame
* fix(core): register the media-clock subpath in its descriptor and keep the reason beside the test
* fix(core): media seeks lead by 10 us so Chrome's timestamp rounding never shows the prior frame
* fix(core): generated pages lead media seeks by a literal, on every generator branch
* fix(producer): a composition with no timeline-registering script no longer waits 45 s at setup
The render waited the full timeout for every composition that never registers a timeline, such as one driven by canvas or requestAnimationFrame.
* fix(producer): module and importing scripts still count as able to register a timeline
* fix(producer): a failed script keeps the readiness wait, and the page scan runs once
* perf(studio): the layer walk keeps its selector index, so scrubbing into new scenes is cheaper
* perf(studio): the layer walk keeps its selector index, so scrubbing into new scenes is cheaper
* fix(snapshot): video frames keep the colours render gives the same footage
* fix(snapshot): say so once when video colours cannot be matched to render
* test(snapshot): cut the HEVC fixture's encode time so the flake gate stays inside its timeout
* style(snapshot): format the HEVC fixture line
* fix(producer): convert HEIC images to JPEG at compile time
Tiled HEIC photos probe as several video streams, so the media-type
preflight rejected them as image:video, and Chrome cannot decode HEIC.
Sniff the ftyp brands of every <img>, join and rotate the tile grid with
ffmpeg, verify the declared size, and swap in a cached JPEG.
* fix(producer): shorten the HEIC prep comments
* fix(producer): name host tool failures and keep a failed HEIC preview image as authored
Also: HEIC tests run in the integration lane; the primary grid is picked by default disposition.
* chore(producer): raise the package size budget for the HEIC prep

* feat(cli): check catches audio the render would lose or play as silence
check gains an Audio section, read from the media list the render mixes:
- error: a clip's source has no audio the render can read (its mix fails,
the film ships without sound)
- warning: a clip starts past the end of its file, or the part it plays
is silent
- info: the film has no sound at all
The bundle and media list are now built once and shared with the HDR
inspection; the audio pass runs while the browser pass does.
Fixes#2775
* fix(cli): check reports an unreadable audio source the way render handles it
A source with no audio track is refused by render's own media-type rule, now exported from the producer and called by check; a source that does not decode as audio fails the mix and stops the render.
* perf(cli): check samples a long clip at a few spots before reading all of it for silence
Sound at any spot ends the decode; a clip is only called silent after its whole played part is read.
* chore(cli): drop a comment the shared finding helper's name already says
* fix(core): a composition behind a wrapper takes its host's start
Fixes#4334.
* fix(core): a composition inside a timed wrapper starts with the wrapper
The nearest host or timed wrapper above a mounted root sets its start, so its clock starts when the wrapper shows it, matching how CSS animations already pick their clip.
* test(producer): re-pin the test classification digest
* fix(engine): name where a root composition script threw and the element it looked up
* style(engine): format throw-site helper
* fix(engine): shorten the throw-site comment
* fix(engine): name a lookup only when the throwing line holds exactly one
* feat(cli): hyperframes <dir> opens the project in the app
* refactor(cli): one command-word lookup and one rewritten command line for the folder shortcut
* refactor(cli): shorten the folder shortcut comments to fit the comment ratchet
* fix(producer): deduplicate scene font faces before embedding
* fix(producer): address font deduplication review
* docs(help): document render font-face deduplication
The troubleshooting guide this section originally targeted was folded
into docs/help.mdx on main, so the section now lives under the render
troubleshooting entries there.

* fix(core): the fonts gate starts loading declared faces no laid-out text uses yet
Before composition scripts run, waitForFonts forces one layout and awaits
document.fonts.ready. A face that only script-built text uses has not started
loading at that point, so ready does not wait for it and the script measures
the fallback face. Start every face still unloaded after the forced layout,
under the existing timeout; a load that rejects falls through to the same
timeout warning instead of stopping the scripts.

The examples topic listed title-card and video-edit, which do not exist,
and none of the eight examples in registry/examples. List blank plus the
registry examples with their registry-item descriptions, and add a test
that fails when the topic and registry/examples disagree.
Fixes#5393
* fix(producer): a media src that resolves to the page itself is no source
A src of '#', '#t=1', '?' or '?x=1' reads back from the browser as the page URL
plus a suffix. decodedUrlPath strips the suffix, so the probe opened index.html as
a media file and failed the render with 'media sources are text documents'.
Discovery now drops any src whose URL without query and hash equals the page URL,
which also covers the blank and whitespace forms from the earlier fix.
* fix(producer): name the page-itself check instead of commenting it
The beginFrame probe now tells a timeout from a real rejection.
A timeout relaunches Chrome and probes once more with a longer budget.
An unsupported answer still falls back at once.
The off-canvas indicators (always mounted) and the Layers panel rebuild their layer list every
100 ms while a scrub mutates the preview, and each rebuild read the computed style of every element
of every scene, on screen or not. The runtime already hides everything inside a clip its visibility
pass hid, so those subtrees hold no layer: the walk now skips a clip marked data-hf-clip-hidden
with an inline visibility of hidden. The marker constant moves to studio-preview-mark so the runtime
and Studio share one owner.
* fix(producer): a render whose capture stops advancing fails within minutes
* fix(producer): keep the bounded probe read the stall change dropped
* chore(producer): shorten a test comment
* fix(producer): every retry batch gets its own first-frame window; the stall test waits for the render to settle
A retry that runs as several batches opened one stall window for the whole attempt, so a later batch whose browsers take longer than the no-progress window to land a frame was killed where main would have finished. The window now opens per batch. The stall tests also waited a fixed number of turns for real file IO after the last frame, which failed about 3 runs in 10 on a loaded machine; they now wait for the render to settle.
* fix(producer): a test reads the stall error fields instead of suppressions; size budget follows
* test(producer): split the scripted capture attempt into small helpers
* test(producer): the stall test advances fake time only while the scripted capture waits
