  surface: "primes"
  role: "cutout-arrangement"
  formats_available: ["avif", "webp"]
  ground: "clear — the black behind the cutouts was the scanner lid seen through a clear sheet, so every tier keys it to transparent; a page gives the piece its ground"
  orientation: "the marker sign runs sideways, reading bottom to top"
  alt_text: "Cutouts on a clear sheet: the applied-math card (Design is applied linguistics, Data science is linguistic physics) above a sideways marker sign, PUBLIC HOME SCHOOL AND PUBLIC BRAIN PLAY, red and yellow on teal beside book spines"
  tiers: {
    thumb: { width: 190, height: 256, avif_kib: 8, webp_kib: 7 }
    display: { width: 381, height: 512, avif_kib: 28, webp_kib: 22 }

^"optimization"{
  tool: "image-optimize illustrations tiers (magick → cwebp / avifenc), from a -strip intermediate at 2048px"
  png: "none — AVIF and WebP only, as the September sets ship"
  alpha: "the lid keyed before tiers are cut: a 5x5 median, dark under 30% and neutral under 10% chroma, a core that survives a wide opening, regrown a little inside a fine mask, reached from the scan edge; light slivers in an 8px edge band clear where they meet the lid, and pure white reached from the edge is uncovered glass"
  hero_budget: "hero at quality 75, under 120 KiB"
  metadata: "none embedded; the intermediate is stripped before any tier is cut"
