/* ═══════════════════════════════════════════════════════════
   THE CINEMATIC ARCHIVE — videos.php
   ═══════════════════════════════════════════════════════════

   The old archive was 127 identical white cards in three columns, each holding
   a full X embed. Three things were wrong with it and only one was cosmetic:

     1. It was ~21,000 px tall and every row looked like every other row, so it
        could be scrolled but not scanned.
     2. Every card was a third-party iframe, so the page cost tens of MB.
     3. Nothing on it said which year you were in except a 2rem heading.

   So the structure changed, not the paint. The year is now the largest object
   on the page and doubles as the navigation. Below it the videos are a dense
   index — 127 tiles you can take in at a glance — and the embed is built only
   for the one you click. Zero iframes on load.

   Every colour, size, space and duration here comes from style.css tokens.
   Zero !important. */
