- fan modal: stage block w. idle-reveal/careen-out; carousel shifts left so focused card sits left-of-center; SPIN rotates whole card via Element.animate(); FLIP toggles polarity (Levity ↔ Gravity) via perspective rotateY w. mid-flip repaint; SPIN state retained across FLIP; FLIP btn hover-revealed only when focused card or btn is hovered (:has)
- mobile breakpoints: --fan-card-w / --fan-card-h / --fan-stage-shift / --fan-carousel-step lifted to CSS vars on .tarot-fan-wrap; portrait ≤ 480px @ 150×230, landscape ≤ 500h @ 150×235; corners + face text/padding scale w. card width
- shared StageCard JS module (apps/epic/stage-card.js): fromDataset, populateCard, populateKeywords, buildInfoData, renderFyi — sig/sea/fan all delegate; ~150 lines de-duplicated
- shared @mixin stat-block-shared (SCSS) lifts duplicated stat-face / stat-keywords / sig-info rules; @mixin stage-card-polarity unifies sea-stage--levity/--gravity + fan[data-polarity] coloring
- model rename: TarotCard.reversal → reversal_qualifier (migration 0014); render-time fallback to current polarity's qualifier when blank
- class unification: .sig-info-open / .sea-info-open / .fyi-open → .fyi-open (on stat block); .sig-flip-btn / .sea-spin-btn / .fan-spin-btn → .spin-btn; same for .fyi-btn / .fyi-prev / .fyi-next
- custom combobox (apps/epic/combobox.js) replaces native <select> for PICK SEA spread picker — keyboard nav, click-outside-close, aria roles; Firefox/Chrome OS-rendered <option> ignored CSS
- Jasmine: FanStageSpec.js w. idle-reveal / population / SPIN / FYI / FLIP specs; sig + sea fixtures + IT view assertions updated for renamed classes
- 748 ITs + Jasmine green
