   Gallery wall of warm light: achromatic system — Concrete #f5f5f5 canvas,
   white cards at 20px with 48px padding, black full-bleed sections, 80px
   pill buttons, weight-400 poster type at massive scale with line-height
   1.0, announcement bar, non-sticky white nav, section rhythm by
   background alternation (concrete → white → black). Zero chromatic
   accents — the only warmth is the screen glow illustration. */
