/* ════════════════════════════════════════════════════════════════════
   VIDEOS — shared stylesheet for /videos, the video index.

   Self-contained page chrome: tokens, navbar, footer, and the card grid.
   Same design language as guides.css (DM Serif + DM Sans, dark UI,
   purple/pink accent) so the hub reads as part of the site.

   This is a hub, not an article. It indexes the videos and points each
   one at the article it belongs to — it never restates the article's
   content, so it competes with nothing.
