/*
 * album.css — ALBUM page (route /album, js/pages/album.js).
 * 2026-09-10 redesign to a left chapter-rail + right card-grid layout
 * (per a user reference screenshot): compact rarity-framed cards with an
 * orb icon + colored name banner + an "N/M materials" bar, opening a
 * detail modal on click. Kept DEEPCORE's cream-on-tan palette; the
 * reference's rarity idea maps to a per-chapter frame colour (--tier).
