/*
 * Identite visuelle Maison YaniAm (voir plan Task 20,
 * docs/superpowers/plans/2026-09-18-maison-yaniam-gallery-visual-scale-v1.2.md) :
 * tokens, typographies et langage de forme repris tels quels de
 * yexibit/maison-yaniam-site (css/style.css), pour que la galerie porte la
 * meme identite premium que le site vitrine. Seul le rythme d'espacement
 * est adapte : la galerie est un outil de consultation dense (jusqu'a
 * 500-700 photos, voir Task 21), pas une page marketing.
 *
 * Polices Google Fonts (meme import que le site) : aucune autre ressource
 * externe, tout le reste reste local pour l'hebergement mutualise OVH (voir
 * ARCHITECTURE.md).
