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.
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.
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
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
When linkedom parses a fragment like `<div data-composition-id="X">...
</div>`, the div becomes the documentElement and body is empty.
contentDoc.body?.innerHTML returns "" losing the composition wrapper.
Fall back to contentDoc.documentElement?.outerHTML when body content
is empty, preserving composition IDs for sub-compositions where the
host data-composition-id differs from the inner root's.
Fixes style-1-prod regression (captions sub-comp has host id
"captions-comp" but inner root id "captions").

Both the core bundler (htmlBundler.ts) and the producer (htmlCompiler.ts)
had parallel ~200-line implementations of sub-composition inlining. This
divergence caused bug #911 (producer didn't set data-composition-file).
Extract the shared logic into core/compiler/inlineSubCompositions.ts:
- Single function handles: template/body extraction, CSS/script scoping,
asset path rewriting, data-composition-file attribution, content injection
- Callers provide environment-specific callbacks (HTML resolution, parsing,
variable handling, inner root flattening)
- Core bundler passes its advanced features (runtime IDs, variables,
inline style rewriting, inner root flattening)
- Producer passes a simpler resolver (map + filesystem fallback) and
adds pixel sizing post-hoc
Net: -215 lines, one source of truth for sub-comp inlining.
