Person hero glow-up:
- Cinematic ambient — blurred portrait + an accent colour mesh + vignette, masked
to fade into the page (was a flat wash).
- Portrait gets a slowly-rotating accent gradient ring (masked donut, GPU
transform) and a gentle float; an accent ring + glow frame.
- An accent role tagline ('ACTOR' / 'DIRECTOR' …) above a gradient-filled name,
plus a credits-count chip. Honors prefers-reduced-motion.
Performance:
- Long filmography grids use content-visibility:auto + contain-intrinsic-size so
the browser skips off-screen cards (cheap scroll), and skip replaying the
entrance animation as cards recycle.
- Hero layers are static (painted once); only two tiny composited transforms
animate. Posters/photos stay on small TMDB sizes + lazy-load; trending cached;
search debounced + request-sequenced.
Pure visual/perf layer — same data + isolation. Shell/JS tests pass.
