   Media section (home page). Shares the Technology backdrop and tokens
   (css/tech.css) but has its own shape: a cinematic feature banner with the
   thumbnail bleeding across the card under a scrim, a row of filter chips,
   and a scroll-snapping filmstrip of poster tiles with the titles set into
   the image. Rendered by js/media-section.js from blogs.js.
