/* Smart Apothiki — motion layer.
 *
 * Rules this file keeps:
 *  - Only opacity and transform are animated.
 *  - Entrance animations use fill-mode "backwards": once they end, no transform
 *    stays on the element, so position:fixed children (modals, drawers,
 *    dropdowns) are never trapped. <main> and layout wrappers are never animated.
 *  - Elements that contain fixed/modal children are skipped entirely.
 *  - prefers-reduced-motion: everything becomes instant (bottom of the file).
