/*
 * Dalia gallery lightbox — one visual for all three surfaces (G1, 2026-07-23).
 *
 * Source: gallery-shared.css:56-109 (token-clean guest block) + video chrome
 * and arrow reveal lifted from lightbox.css.
 *
 * HARD RULE: this file may only depend on dalia-portal.css tokens
 * (--lilac-400, --lilac-500, --paper, --ink, --font-sans, --ease).
 * It must NEVER reference --cream/--ivory/--charcoal/--stone/--red/
 * --warm-black — the social surface does not define them and the lightbox
 * would fall through to a transparent backdrop (see lightbox.css:11-17).
