/* Case studies: the grid and the spreads (Lucy, 2026-10-25, from the look test
   https://claude.ai/artifact/CtBpdLpsYyzRin3dph8WLX: "L1 Spreads, opened by L3's grid").
   habitabull.html, case-study.html (Driftwood), reptools.html, h2know.html, eternal-wreckening.html, loop.html and
   magnet-fishing.html open on a one-screen bento grid (Trance did too, until it was archived on 2026-11-01): the problem, role, time and
   tools, the numbers, the four strongest screens, the outcome, what I learned and the deck. Every tile is a link
   that jumps to its spread. Then one still spread per chapter: the claim, three lines, several screens shown
   together and whole, the detail behind "+ Read more", sides alternating. Nothing moves like a slideshow: no
   timers, no progress bars, the pictures rise a few pixels once as a spread arrives, never under reduced motion.
   Behaviour lives in components/case-spreads.js. Prefix: cx-. The tiles and cards take the hero's palette at night
   and a paper palette in light mode; screenshots are never pixelated, filtered or cropped (only he is pixel art). */
