/* Lightbox — TV-first, 10-foot UI.
 * Performance rules (LG webOS 24 = Chromium 108 on a modest SoC):
 *  - animate only transform + opacity (compositor-only, no layout/paint)
 *  - no backdrop-filter, no animated box-shadow (shadow = pre-painted ::after, opacity only)
 *  - one static blurred backdrop, rasterised small then scaled by the compositor
 *  - everything sized in rem; rem tracks the viewport so 1920×1080 = 20px
