/* =====================================================================
   FROST STUDIO — page « Le studio » (studio.css).
   Extension narrative de l'accueil, ouverte depuis la section À propos :
   une page éditoriale qui commence dans la photo du fondateur et devient
   de plus en plus minimale — matière, archives, cultures, puis seulement
   des mots, puis « Frost Studio. » et une phrase. Même ADN que le site :
   obsidienne, os, gris froid, typographie énorme, serif en contraste,
   transitions lentes, grands vides. Aucune carte de compétences, aucune
   barre, aucun logo d'outil, aucune frise CV.
   Mouvement : révélations à l'entrée ([data-reveal] → .is-in), progression
   par chapitre (--p de 0 à 1, studio.js), phases du chapitre 05
   ([data-phase]). prefers-reduced-motion : tout est posé, rien ne bouge.
