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
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.
