/* ============================================================
 *  SKELETON LOADERS  (shared, site-wide)
 * ------------------------------------------------------------
 *  Lightweight shimmer placeholders shown while async lists
 *  load, instead of a blank panel or "Loading…" text. Used by:
 *    - the chat widget conversation list  (chat-widget.hbs)
 *    - the /social/chat sidebar            (chat-main.js)
 *    - the activity feed dropdown          (activity-panel.js)
 *
 *  Loaded globally from views/partials/menu.hbs so every surface
 *  can reference the same classes. The shimmer is a single
 *  transform-animated overlay (cheap, GPU-friendly) and respects
 *  prefers-reduced-motion.
