Caption components are overlays — their root element should not
intercept pointer events, allowing clicks to pass through to the
underlying composition content in Studio.
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
- clip-wipe: slower reveal (0.3s), longer hold, smoother exit
- glitch-rgb: 2.5x larger RGB split, stronger scanlines, more dramatic jitter
- gradient-fill: smoother word transitions (0.15s), longer exit
- typewriter: extended group hold times so text lingers on screen
- weight-shift: per-word font-weight animation (200→900), was broken
with only line-level shift that never triggered on single-line groups
- Add caption-highlight: red background sweep behind active word (TikTok-style)
- Re-rendered and uploaded preview videos for all 6 components
