A.7-polish my_sea slot image-rendering (server-saved + mid-draw JS) + non-polarized single-deck-stack collapse — TDD. End-of-session wrap-up 2026-05-25 PM. Three changes covering my_sea.html surfaces that weren't in A.5/A.7's central-sig-only scope: (1) saved-hand slot rendering (_my_sea_slot.html server-rendered partial fired when a draw is resumed via refresh); (2) mid-draw slot fill (sea.js's _fillSlot writes slot.innerHTML on each card-deposit click; previously rendered corner-rank + suit-icon only, NOW renders <img> when card.image_url is non-empty); (3) deck-stack collapse for non-polarized decks (Minchiate today) — the bottom-right of my_sea.html showed two side-by-side GRAVITY + LEVITY stacks regardless of equipped-deck polarization; for non-polarized decks polarity has no meaning so the dual layout misleads. **Critical lock**: collapse is my_sea-ONLY. room.html keeps the dual stacks since multiple gamers contribute (each might bring a different polarization). Server-side template branches {% if request.user.equipped_deck.is_polarized %} to pick dual vs. single rendering; the --single stack carries the actual deck back-image via <img class="sea-stack-face-img"> (object-fit: cover) when has_card_images=True. Sub-changes: card_dict() in apps/epic/utils.py now includes image_url + arcana_key fields so the picker grid's JSON payload carries the data the JS fill-handler needs (single source of truth shared w. the gameroom sea_deck endpoint — apps/gameboard/views.py's saved_by_position dict gets the parallel additions for server-rendered saved hand). SCSS: extended the shared image-mode rule's comma-list selector in _card-deck.scss to include .sea-card-slot.sea-card-slot--image so the contour stroke + depth shadow apply to both saved + mid-draw slots from a single rule definition. Also added .sea-deck-stack--single .sea-stack-face block w. neutral --priUser/--terUser palette (vs. gravity's --quiUser/--quaUser + levity's --terUser/--ninUser) + the corresponding hover/active glow rule positioned AFTER the $_sea-shadow SCSS variable definition at line 1808 (initial draft hit a compile error: Undefined variable: "$_sea-shadow" because the hover rule was placed before the variable was defined; SCSS variables are scope/order-dependent). JS: _fillSlot in sea.js branches on card.image_url — when non-empty, write <img class="sig-stage-card-img"> + add .sea-card-slot--image marker + data-arcana-key attr; otherwise legacy corner-rank + suit-icon. innerHTML alt-attribute properly escapes " to &quot; so card names w. quotes (none today, but defensive) don't break HTML. Existing JS that activates a clicked stack (_activeStack flow + _showOk / _hideOk) works unchanged w. the single-stack variant since the selector .sea-deck-stack matches all variants regardless of polarity suffix; the isLevity = stack.classList.contains('sea-deck-stack--levity') check at the deposit moment returns false for --single → defaults to gravity polarity assignment, which is fine for non-polarized decks (polarity field has no card-content effect). Memory updated: project_image_based_deck_face_rendering.md now lists A.0-A.7 done + this polish + room.html (A.8) as the sole remaining surface for tomorrow. The 6-surface scope sheet shows A.8 as the last red box; everything else green. Tests: 1306/1306 IT+UT total green (73s). No new ITs in this commit — the saved-slot render touch was an extension of existing saved_by_position view context shape (covered by existing slot-render tests' implicit invariance); the JS change is hard to test via Django ITs (would need Jasmine spec or FT, deferred); the deck-stack collapse is a template branch (visual; user verified live in browser this session). Tomorrow: A.8 room.html image-rendering (multi-user surface via Channels WebSocket payload + same template branch pattern; keep dual gravity/levity stacks per user spec)
