/* ---------- HOVER-FLICKER FIX (site-wide) ----------------
   Cause: a `transform: scale` transition on an image whose ancestor card
   also transitions `transform` (lift), both inside `overflow: hidden`,
   makes Chromium re-rasterize/blink while the pointer rests on the photo.
   Fix: give every clipping media-container its own stable compositing
   layer, and promote the scaled child + lifting card to their own layers
   so the scale composites cleanly instead of repainting each frame. */
