Keep every animation transform/opacity-only so frames never repaint:
- hero ring and loading glow pulse via opacity instead of background-position / box-shadow
- button shine sweeps with transform, not left
- floating glass chips drop animated backdrop-filter (it re-samples every frame)
- promote continuously animated layers (particles, halo, float) with will-change
- drop the negligible blur on moving clouds and remove the unused gradient-shift
