/*
 * MeowTarot — Phase 3: Visual Redesign (Global Chrome + Card-Slot Fallback)
 * css/phase-3-redesign.css
 * ─────────────────────────────────────────────────────────────────────────
 *
 * RISK LEVEL: Medium
 * SCOPE: Global chrome (header, bottom-nav, footer) re-skinned with --mt-*
 *        tokens, plus card-slot gradient fallback scoped to
 *        body[data-page='daily'] and body[data-page='question-draw'].
 *
 * REFERENCES the --mt-* token namespace added in css/theme-tokens.css.
 *
 * SPECIFICITY NOTE (Phase 3.3):
 *   Chrome selectors here use a `body[data-page]` prefix — attribute-only,
 *   no value — to match every page that exposes data-page (all of them).
 *   This raises specificity to (0,2,1), tying or beating the pre-existing
 *   `body[data-page='home']` scoped rules in phase-1-home.css §2 and
 *   phase-2-1-logo.css §2. Combined with phase-3-redesign loading LAST in
 *   the stylesheet stack (after phase-1-home), source order resolves ties
 *   in phase-3's favor.
 *
 * WHAT THIS FILE DOES NOT TOUCH:
 *   - Page backgrounds (per-page; later phases)
 *   - .card .front (the art face)
 *   - .card-back PNG assets (asset task, filed separately)
 *   - Result pages, profile, share poster
 *   - css/styles.css flip block (edited separately in Phase 3)
 *
 * LINK ORDER: must load LAST. After phase-1-home.css on the homepage.
 * ─────────────────────────────────────────────────────────────────────────

/* §2 — Card-slot fallback gradient (daily + question-draw selection only)
 *
 * The card-back visual on these pages is actually an <img class="card-back">
 * loaded from a per-deck PNG asset (see js/main.js applyCardBackBackground).
 * The real visual identity lives in those assets, not in CSS.
 *
 * This rule paints the parent .card-slot with the new plum-to-rose
 * gradient as a graceful FALLBACK — visible only if the PNG fails to
 * load (e.g. CDN miss, offline). When the asset loads, the opaque <img>
 * covers this layer entirely.
 *
 * The headline card-back redesign is an asset task tracked separately
 * (generate new plum-to-rose card-back PNGs for all decks, upload to R2).
 *
 * Selectors already have body[data-page='...'] specificity (0,2,1), so
 * the Phase 3.3 prefix uplift does not need to apply here.
