/* ── Resources ──────────────────────────────────────────────
   The video shelf (views/resources.js) in the landing's design: .lp gives it
   the landing canvas, light/dark tokens and blue accent. Type-led: a Geist
   heading, topic chips, then one hairline-separated section per topic. Tiles
   are the cover and two lines of text, no card box; the cover is the only
   framed thing. On phones each tile becomes a compact row. */
