+# V3.17: Mobile Portrait Layout
+
+**Version:** 3.1.1
+**Commits:** `4fcdf13`, `fb3bd53`
+
+## Overview
+
+Full mobile portrait layout for phones, triggered by JS `matchMedia` on narrow portrait screens (`max-width: 500px`, `orientation: portrait`). The desktop layout is completely untouched — all mobile rules are scoped under `body.mobile-portrait`.
+
+## Key Features
+
+### Responsive Game Layout
+- Viewport fills 100dvh with no scroll; `overscroll-behavior: contain` prevents pull-to-refresh
+- Game screen uses flexbox column: compact header → opponents row → player row → bottom bar
+- Safe-area insets respected for notched devices (`env(safe-area-inset-top/bottom)`)
+
+### Compact Header
+- Single-row header with reduced font sizes (0.75rem) and tight gaps
+- Non-essential items hidden on mobile: username display, logout button, active rules bar
+- Status message, round info, final turn badge, and leave button all use `white-space: nowrap` with ellipsis overflow
+
+### Opponent Cards
+- Flat horizontal strip (no arch rotation) with horizontal scroll for 4+ opponents
+- Cards scaled to 32x45px with 0.6rem font (26x36px on short screens)
+- Dealer chip scaled from 38px to 20px diameter to fit compact opponent areas
+- Showing score badge sized proportionally
+
+### Deck/Discard Area
+- Deck and discard cards match player card size (72x101px) for visual consistency
+- Held card floating matches player card size with proportional font scaling
+
+### Player Cards
+- Fixed 72x101px cards with 1.5rem font in 3-column grid
+- 60x84px with 1.3rem font on short screens (max-height: 600px)
+- Font size set inline by `card-manager.js` proportional to card width (0.35x ratio on mobile)
+
+### Side Panels as Bottom Drawers
+- Standings and scoreboard panels slide up as bottom drawers from a mobile bottom bar
+- Drawer backdrop overlay with tap-to-dismiss
+- Drag handle visual indicator on each drawer
+- Drawers auto-close on screen change or layout change back to desktop
+
+### Short Screen Fallback
+- `@media (max-height: 600px)` reduces all card sizes, gaps, and padding
+- Opponent cards: 26x36px, deck/discard: 60x84px, player cards: 60x84px
+
+## Animation Fixes
+
+### Deal Animation Guard
+- `renderGame()` returns early when `dealAnimationInProgress` is true
+- Prevents WebSocket state updates from destroying card slot DOM elements mid-deal animation
+- Cards were piling up at (0,0) because `getCardSlotRect()` read stale/null positions after `innerHTML = ''`
+
+### Animation Overlay Card Sizing
+- **Root cause:** Base `.card` CSS (`width: clamp(65px, 5.5vw, 100px)`) was leaking into animation overlay elements (`.draw-anim-front.card`), overriding the intended `width: 100%` inherited from the overlay container
+- **Effect:** Opponent flip overlays appeared at 65px instead of 32px (too big); deck/discard draw overlays appeared at 65px instead of 72px (too small)
+- **Fix:** Added `!important` to `.draw-anim-front/.draw-anim-back` `width` and `height` rules to ensure animation overlays always match their parent container's inline dimensions from JavaScript
+
+### Opponent Swap Held Card Sizing
+- `fireSwapAnimation()` now passes a `heldRect` sized to match the opponent card (32px) positioned at the holding location, instead of defaulting to deck dimensions (72px)
+- The traveling held card no longer appears oversized relative to opponent cards during the swap arc
+
+### Font Size Consistency
+- `cardFontSize()` helper in `CardAnimations` uses 0.35x width ratio on mobile (vs 0.5x desktop)
+- Applied consistently across all animation paths: `createAnimCard`, `createCardFromData`, and arc swap font transitions
+- Held card floating gets inline font-size scaled to card width on mobile
+
+## CSS Architecture
+
+All mobile rules use the `body.mobile-portrait` scope:
+
+```css
+/* Applied by JS matchMedia, not CSS media query */
+body.mobile-portrait .selector { ... }
+
+/* Short screen fallback uses both */
+@media (max-height: 600px) {
+    body.mobile-portrait .selector { ... }
+}
+```
+
+Card sizing uses `!important` to override base `.card` clamp values:
+```css
+body.mobile-portrait .opponent-area .card {
+    width: 32px !important;
+    height: 45px !important;
+}
+```
+
+Animation overlays use `!important` to override base `.card` leaking:
+```css
+.draw-anim-front,
+.draw-anim-back {
+    width: 100% !important;
+    height: 100% !important;
+}
+```
+
+## Files Modified
+
+| File | Changes |
+|------|---------|
+| `client/style.css` | ~470 lines of mobile portrait CSS added at end of file |
+| `client/app.js` | Mobile detection, drawer management, `renderGame()` guard, swap heldRect sizing, held card font scaling |
+| `client/card-animations.js` | `cardFontSize()` helper, consistent font scaling across all animation paths |
+| `client/card-manager.js` | Inline font-size on mobile for `updateCardElement()` |
+| `client/index.html` | Mobile bottom bar, drawer backdrop, viewport-fit=cover |
+
+## Testing
+
+- **Desktop:** No visual changes — all rules scoped under `body.mobile-portrait`
+- **Mobile portrait:** Verify game fits 100dvh, no scroll, cards properly sized
+- **Deal animation:** Cards fly to correct grid positions (not piling up)
+- **Draw/discard:** Animation overlay matches source card size
+- **Opponent swap:** Flip and arc animations use opponent card dimensions
+- **Short screens (iPhone SE):** All elements fit with reduced sizes
+- **Orientation change:** Layout switches cleanly between mobile and desktop

Add !important to .draw-anim-front/.draw-anim-back width/height: 100% so overlays always match their parent container size. - Size opponent swap held card to match opponent card dimensions instead of defaulting to deck size (looked oversized on mobile) - Shrink dealer chip on mobile (38px -> 20px) to fit opponent areas - Make header more compact: smaller fonts, tighter gaps, nowrap on badges - Bump deck/discard to 72x101px to match player card size on mobile - Add spacing between header/opponents, and between deck area/player cards Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-21 23:11:39 -05:00

adlee-was-taken	c59c1e28e2	Smooth held card transition and scale font with card size Remove scale(1.15) size jump on held card, keep gold border/glow highlight. Set animation card font-size proportionally to card width so text matches across deck, hand, and opponent card sizes. Animate font-size during swaps so text scales smoothly as cards travel between different-sized positions. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-15 00:14:27 -05:00

adlee-was-taken	850b8d6abf	Standard-rules-only leaderboard with client unranked indicators Only standard-rules games now count toward leaderboard stats. Games with any house rule variant are marked "Unranked" in the active rules bar, and a notice appears in the lobby when house rules are selected. Also fixes game_logger duplicate options dicts (now uses dataclasses.asdict, capturing all options including previously missing ones) and refactors duplicated achievement-checking logic into shared helpers.

adlee-was-taken	e1cca98b8b	Fix client scoring to respect house rules for column pairs Client-side scoring (points badge and score tally animation) ignored house rules that modify pair behavior. Extract shared calculateColumnScores() helper that mirrors server logic for eagle_eye, negative_pairs_keep_value, wolfpack, four_of_a_kind, and one_eyed_jacks rules. Server now sends scoring_rules flags in game state. Also fix opponent flip animation card font-size matching. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-14 10:34:40 -05:00
