/* === VIDEO PERFORMANCE ===
   `contain: strict` confines layout/paint/style work to the
   card boundary — so a video repainting its frame never
   invalidates anything outside the card.
   `isolation: isolate` forces a separate compositing layer
   without `will-change` (which leaks memory if applied
   permanently to many elements).
   `translate3d(0,0,0)` promotes the layer to the GPU. */
