Add 15 caption overlay components to the registry, covering a wide range of animation techniques: Standalone origins (6): - caption-pill-karaoke: pill container + karaoke word highlight - caption-neon-accent: multi-color neon glow with wiggle drift - caption-weight-shift: font-weight transition between lines - caption-emoji-pop: emoji + stroked text + horizontal squeeze - caption-editorial-emphasis: dual-font (Inter + Playfair) emphasis - caption-parallax-layers: 3D text layering with vertical stretch Gallery picks (9): - caption-glitch-rgb: RGB chromatic aberration + CRT scanlines - caption-typewriter: green terminal char-by-char with cursor - caption-matrix-decode: scramble-reveal character animation - caption-particle-burst: keyword particle explosions - caption-texture-lava: flowing lava texture mask - caption-clip-wipe: clip-path left-to-right wipe reveal - caption-kinetic-slam: full-screen single-word slam - caption-gradient-fill: gradient-clipped text + elastic bounce - caption-neon-glow: cyan/magenta neon glow accents Each component includes the reusable HTML, a demo composition, and registry-item.json. All use a generic HyperFrames transcript. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
