/* ==================== Reels (Facebook-style paged viewer) ====================
   Left sidebar (For you / Following / Profile) + one reel at a time in a
   fixed-size player, with like/comment/save/share off to its side and
   up/down arrows to page between reels.

   The visible reel is rendered as `.post-card.reel-stage-card` — reusing
   that class is what lets attachFeedHandlers() from post-render.js drive
   like/save/comment/reply/delete here with no duplicated logic.
   `display: contents` on the card lets its two visual pieces (the player
   and the action rail) lay out as direct flex children of
   .reels-player-row — i.e. side by side on screen — while remaining one
   semantic element for data-post-id / querySelector purposes; the comments
   drawer is `position: fixed` so its place in the DOM doesn't matter either.
   Only this layout, the pager, watch-based view tracking, follow buttons,
   and the create-reel upload flow are Reels-specific — everything else is
   shared with the rest of the app. */
