 * 1. Concept: an East Asian ink painting (sumi-e) hung as a poster. Rice paper, black ink, one vermilion seal.
 * 2. Type: Shippori Mincho B1 (dramatic display, 500/800) + Zen Kaku Gothic New (quiet text, 400/700), self-hosted.
 * 3. Palette: paper #f4efe4, wash #ebe4d4, ink #151311, ash #5a544c, vermilion #b3311b (seal #c23b22, on ink #e0614a).
 * 4. Layout signature: ARCHETYPE poster/affiche. Home = one giant title across the viewport over an ink dragon,
 *    a red seal and nothing else; below, poster sheets with oversized numbers. Pages = huge title, vertical
 *    label strip in the margin, narrow column.
 * 5. Finishing detail: the seal stamp recurs as the only colour (logo, h2 marks, list marks), products hang as scrolls.
