User spec 2026-05-26 for the sea_stage modal (shared by my_sea.html today, room.html SEA SELECT later): 1. **Reversed card opens rightside-up, then slowly auto-rotates 180°.** Preserves the original text-card legibility convention (modal opens w. upright frame + dimmed upright title + highlighted upside-down reversal title) but adds a JS-driven 0.8s rotate-in (2× the SPIN transition's 0.4s) that lands the card upside-down. Stat-block still gets `.is-reversed` immediately so the REVERSAL label is highlighted from the first frame. `_populate` no longer slaps `.stage-card--reversed` on the card up front; `_showStage` schedules `_autoRotateToReversed` 400ms post-flip-in (past the 0.35s `sea-flip-in` keyframe + buffer). Auto-rotate mirrors the SPIN-click pattern — strip the flip-in keyframe class, force reflow, inline-override `transition-duration` to 0.8s, then toggle `.stage-card--reversed` so the static `transition: transform` lerps the rotation. Timers tracked on module-level handles so dismiss-mid-rotate + reopen-mid-rotate cancel cleanly w.o. stacking handlers (cleared in `_populate`, `_hideStage`, `_testInit`). 2. **FLIP btn always lands at visual bottom-left, regardless of reversal.** Previously the in-card btn rode along w. the 180° rotation, ending top-right (user-flagged as wrong: "the game_kit.html carousel already handles this perfectly—FLIP only ever appears bottom-left, regardless of reversal"). The fan-flip-btn pulls this off by being a SIBLING of `.tarot-fan-wrap` (lives outside any rotating card) — sea_stage's btn sits INSIDE `.sea-stage-card` along w. my_sign / my_sign-applet's shared DOM, so restructuring out wasn't an option. Solved via CSS counter-positioning instead: `.sea-stage-card.stage-card--reversed .sea-stage-flip-btn` re-anchors to card-local top-right + counter-rotates 180° on the btn itself, landing it at visual bottom-left w. upright label. Companion `[data-spinning]` attr (joined to the existing flip-btn-mid-flip selector chain) hides the btn during the rotation window so it never jumps visibly between corners. Set by both `_autoRotateToReversed` (0.8s window) + the SPIN click handler (0.4s window). TDD coverage — `SeaDealSpec.js` gets a new describe block w. jasmine.clock-driven specs: - `reversed-card open` × 6: `is-reversed` set immediately on stat-block; `.stage-card--reversed` NOT set immediately on card; `data-spinning` NOT set pre-flip-in; both set after 500ms; both cleared (well, `.stage-card--reversed` persists) after 1400ms; upright cards don't trigger auto-rotate at all - `SPIN click hides FLIP via [data-spinning]` × 2: set on click; cleared after 500ms Files: - `apps/epic/static/apps/epic/sea.js` — `_populate` defers `.stage-card--reversed` + clears in-flight rotate state; `_showStage` schedules `_autoRotateToReversed` for reversed cards; SPIN handler sets `data-spinning` for the SPIN_MS window; `_hideStage` + `_testInit` clear rotate timers + spin attr; new module-level timer handles + duration constants - `static_src/scss/_card-deck.scss` — `.sea-stage-card.stage-card--reversed .sea-stage-flip-btn` counter-positioning rule (bottom→top, left→right, transform: rotate(180deg)); `[data-spinning]` joined to the unified flip-btn mid-rotate-hide selector chain - `static_src/tests/SeaDealSpec.js` + `static/tests/SeaDealSpec.js` — new describe blocks for the two new behaviors Jasmine FT green. User-verified visually on `/gameboard/my-sea/` w. an upside-down reversed-card open: "Visually verified just now in my_sea.html, very nicely done".
