  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"

  metadata: "none embedded; the intermediate is stripped before any tier is cut"
