An inert <hf-color-group> holds a lane's data-color-grading; <video>, <img>
and <canvas> join with data-color-group. A member's own grading overrides
its group's. The runtime discovers members, regrades them when the group's
grading or a member's data-color-group changes, and ungrades them when the
group element or its grading goes, drawing only members on screen.
Render keeps group-graded video at full size like directly graded video,
and lint accepts (and still validates) grading on hf-color-group.

* feat(lint): warn when a sub-composition's linked stylesheet names its root id
* chore(skills): regenerate the skills manifest
* fix(lint): the linked-stylesheet hint names fixes that lint clean
* docs: one Troubleshooting page, four tabs, and the start pages folded
* docs: keep how Studio app updates arrive on the help page
Folding the Studio app troubleshooting page into /help dropped its
"How updates arrive" section: the update button, Settings > Updates
and the Mac menu route, the Automatic updates toggle, and what to do
when an update stalls or cannot check. It is back word for word; every
label is still in the app.
* docs(studio): the browser editor in six pages, named the browser editor
* docs(studio): mute where the editor has it, and no solo control
The audio pages still described a solo control and a group-row mute that
the editor does not render. Muting is the speaker button on an audio
track (Mute track / Unmute track), the same toggle on a selected clip,
and the Muted switch; a group is silenced through its members' tracks.
The audio reference drops its solo section for the same reason.
* fix(core): a self-closed audio group no longer hides the clips after it
HTML does not close a custom element on `/>`, so `<hf-audio-group id="sfx" />` takes in every
later sibling, and the runtime's inert style (`display:none`) hid them in preview, snapshot and
render. The style is now `display:contents`: an empty group still makes no box, and anything
inside one renders as written. A lint warning names the elements a group holds, and the docs and
mixing reference show the group closed.
* style(core): cut the audio group comments to the comment length limits
* fix(core): a muted audio group still hides what sits inside it
A muted bus (`data-hidden`) is hidden by an inline display:none that the bus rule outranked, so
clips inside a muted self-closed bus kept painting while their audio and video frames dropped.
A sub-composition file with a <template> is mounted from the template alone, so a <style>
in its <head> (or a stylesheet link in its body) never applies in preview, snapshot or render.
Warn on it, with the fix in the message: move it inside <template>.
* fix(core): color grading applies to canvas compositions
data-color-grading on a <canvas> was ignored by the runtime and refused by
lint, the Studio panel and the CLI writer. One source-tag list in the grading
contract now feeds all of them. A canvas is sized from its drawing buffer and
re-uploaded on every seek and transport tick.
* fix(core): keep the comment share of grading files at the base
* fix(cli): timeline lists clips nested in a timed element and lint flags ones that never show
* docs(lint): wrap the nested-clip entries
* docs(skills): format the nested-clip note and refresh the skills manifest
* fix(cli): keep timeline edits from colliding with a clip's own wrapper
* fix(cli): cut clips nested in a wrapper at their sub-composition's in-point
* refactor(lint): split the nested-clip visibility checks to keep the audit green
* style(cli): restore the timeline test's formatting
* docs(lint): add a reference page for every lint finding code
docs/reference/lint-rules.mdx lists every code emitted by the linter
(132: the 121 rule codes in packages/lint/src/rules/*.ts plus the 11
project-level probes that run as part of a project lint) with its
severity, what it catches, and how to fix it, grouped by the rule file
the code comes from. Conditional severities (Studio-host structure
checks, GSAP seek-order hazards) say when they escalate.
Link it from docs/packages/lint.mdx and add it to the Composition
reference group in docs.json.
Issue: #5385
* docs(lint): document the color grading codes and correct four entries
