/*
 * Vitrine — VeloCMS theme (slug: "vitrine")
 * 1:1 port of the founder's Claude-Design canvas "Vitrine Theme.dc.html".
 *
 * "Collector's museum theme." Square corners, hairline rules, grayscale-to-color
 * specimen reveal, catalogue-plate captions.
 * Palette: ivory #F4F1EA · ink #14161A · smoke #3A3E44 · silver #C7CCD1 ·
 *          steel-blue #2E4257 (accent) · ivory-2 #EDEAE1 (niche band panel)
 * Display: Marcellus (single 400 weight) · Body: Source Serif 4 (400/600 + italics)
 *
 * All values below are copied verbatim from the design's inline styles and its
 * 1h engineering-notes spec (color tokens, spacing/radius scale, hover table,
 * motion keyframes, mobile-drawer spec). No rounding, no reinterpretation.
 *
 * Scoped to [data-theme="vitrine"] (NOT main-scoped) so /shop and /products/*
 * resolve the same tokens. P-094 token bridge at the bottom.
