/*
 * jumble page — Instagram-style square-tile grid of photos + videos.
 *
 * Cadence and gap size mirror Instagram: three columns on desktop AND
 * mobile (Instagram never breaks its 3-col rhythm), 1px-ish gap so
 * tiles read as a composition rather than a gallery of cards. Each
 * tile is a strict square via aspect-ratio; media inside covers the
 * square with object-fit: cover so aspect ratios are always uniform
 * on the grid surface (users click through to see the full aspect
 * when it matters).

/* === Media inside — cover the square ================================
   Absolute positioning inside a position:relative tile locks the
   inner media to the tile's aspect-ratio-computed dimensions. This
   avoids a CSS quirk where a <video> or an <a><img> with height:100%
   sometimes falls back to the media's intrinsic height when the
   parent's height is derived from aspect-ratio rather than an
   explicit pixel value — the reason one tile in Peter's first upload
   rendered taller than its neighbours. */

/* === Small play indicator on video tiles ============================
