* 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(sdk): preserve font and image declarations after object edits
* fix(studio): preserve variable object defaults when editing declarations
* fix(studio): show font and image values in bind warnings
* fix(core): resolve a relative data-start inside the clip's own composition
* fix(engine): render-side data-start references resolve in the clip's own composition
The engine's reference resolver still looked an id up document-wide, so
with two different compositions sharing an id the producer placed media
from the first one while the runtime used the clip's own. Scope it the
same way as the runtime's startResolver, with the same document-wide
fallback, and correct the SDK comments that called the runtime lookup global.
* fix(parsers): keep getAttribute-only reference adapters working
The scoped lookup needs parentElement, closest and querySelectorAll, but
RefResolverEl is exported from @hyperframes/parsers and @hyperframes/engine.
Make them optional and fall back to the document-wide lookup when an adapter
lacks them.
* refactor: look up a scoped reference with one id query
* fix(studio-server): keep transparency in proxies of VP8/VP9 alpha webm
A webm whose alpha lives in the VP8/VP9 side channel (alpha_mode=1,
pix_fmt yuv420p) was proxied to opaque H.264, and the VP8 proxy path
decoded it with ffmpeg's native decoder, which drops alpha. The alpha
rule and the alpha-reading decoder now live once in
@hyperframes/parsers/media-alpha, used by engine and studio-server.
* build(parsers): raise the packed size budget for the media-alpha subpath
parsers already sat at its packed budget on main; the shared alpha rule
adds 676 B of JS and 803 B of declarations (190958 B packed in CI).

* 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
duplicate_audio_track compared raw float ends, so 21.03 + 0.1 (21.130000000000003)
overlapped a clip starting at 21.13. The one-instant span helpers move from core's
clipFacts to parsers, which lint and core both depend on; core re-exports them and
the rule uses spansOverlap.
The capability catalog listed correction controls as "adjustments" and
finishing controls as "finishing", while the grading payload calls them
"adjust" and "details", and no capability showed a payload. Agents wrapped a
correction in "adjustments" and the validator rejected it with a hint that
named no key. The schema now owns a correction example; the catalog names its
sections after the payload keys and carries that example, correction and
finishing show an apply payload from it, the unknown-key hint lists the real
top-level keys, and a test validates every grading payload in docs and skills.
audio and timeline joined a clip's src to its composition's folder by hand,
so a project-root asset used from a nested scene, or a percent-encoded file
name, was "not found" although preview, check and render load it.
resolveAuthoredAssetFile now owns that lookup (the sub-composition rewrite,
then the decoded project-root resolve), and audio, timeline and
media-treatment all use it.
