/*
 * ILUSTRA — the carton tile (v5 §5), the market map (v5.1 §3), the record (v5.1 §6).
 * Markup: src/lib/illustrations.mjs.
 *
 * Every tile is a square container (`container-type: inline-size`), so
 * everything inside is measured in cqw and the picture scales as one piece,
 * like an SVG. Text that must stay legible on a phone takes a px floor.
 * Tokens are v5 §2 only; each carries its own fallback while tokens.css lands.
 * Motion: only transform / opacity / filter; ambient loops 6–7 s, paused by
 * [data-paused] on the tile or any ancestor, gone under reduced motion.
