- **Dark mode support** (dark: classes throughout)

---

## Technical Implementation

### Composables Used
- `useWebSocket()` - Connection management, auto-reconnect
- `useGameActions()` - Type-safe action emitters
- `useGameStore()` - Game state and play history

### Store Integration
```typescript
// Game state computed from store
const gameState = computed(() => gameStore.gameState)
const playHistory = computed(() => gameStore.playHistory)
const canRollDice = computed(() => gameStore.canRollDice)

// Runners state conversion
const runnersState = computed(() => ({
  first: gameState.value?.runners.first !== null,
  second: gameState.value?.runners.second !== null,
  third: gameState.value?.runners.third !== null
}))
```

### WebSocket Lifecycle
```typescript
onMounted(() => {
  connect()  // Establish connection

  watch(isConnected, async (connected) => {
    if (connected) {
      await actions.joinGame('player')
      await actions.requestGameState()
    }
  })
})

onUnmounted(() => {
  actions.leaveGame()
  gameStore.resetGame()
})
```

## Next Steps (Phase F3)

**Phase F3: Decision Input Workflow** (Week 3)

Now that game state displays beautifully, we need to add **interactive decision inputs**:

1. **Defensive positioning** - Infield/outfield depth selection
2. **Pitcher focus** - Targeting specific hitters
3. **Stolen base attempts** - Per-runner SB toggles
4. **Offensive approach** - Swing/bunt/hit-and-run
5. **Turn indicators** - Whose decision is needed
6. **Decision validation** - Client-side checks before submit
7. **Mobile-friendly forms** - Large buttons, clear labels

**Components to Create**:
- `components/Decisions/DefensiveSetup.vue`
- `components/Decisions/PitcherFocusInput.vue`
- `components/Decisions/StolenBaseInputs.vue`
- `components/Decisions/OffensiveApproach.vue`
- `components/Decisions/DecisionPanel.vue`
- `components/UI/ActionButton.vue`
- `components/UI/ButtonGroup.vue`

**Estimated Time**: 4-6 hours

2. **Gradients add polish** - Simple gradients make UI feel modern without heavy assets
3. **Animations enhance UX** - Subtle pulse/fade effects make UI feel alive
4. **Color coding works** - Green (runs), Red (outs), Blue (hits) intuitive
5. **Empty states matter** - Friendly messages improve first-time experience
6. **Sticky scoreboard is gold** - Always-visible context improves gameplay

## Known Issues

### Toast Notification Positioning Bug

**Issue**: Toast notifications only render when positioned at screen center (top-1/2, left-1/2). Bottom positioning fails silently.

**Symptoms**:
- ✅ Works: `fixed top-1/2 left-1/2 -translate-x-1/2 -translate-y-1/2`
- ❌ Fails: `fixed bottom-8 left-1/2 -translate-x-1/2`
- ❌ Fails: Using `<Transition>` wrapper around toast div

**Attempted Solutions**:
- Changed z-index from 50 → 100 → 9999 (no effect)
- Removed Transition wrapper (still fails at bottom)
- Changed positioning units (px, rem, vh - all fail)
- Verified v-if toastMessage reactive state (works)
- Console logs show toast state active (works)

**Root Cause**: Unknown - possibly Tailwind transform conflict, Nuxt SSR hydration issue, or viewport calculation bug

**Current Workaround**:
- Demo page uses center-screen position (working)
- Production components should implement UI store toast system instead
- File: `frontend-sba/pages/demo.vue:165-177`

**Priority**: Low (demo-only issue, not affecting production components)

**Next Steps for Fix**:
1. Test with Pinia UI store toast system
2. Try absolute positioning instead of fixed
3. Debug with browser DevTools element inspector
4. Check if `<Teleport>` to body helps

---

**Status**: ✅ Phase F2 Complete - Ready for Phase F3 (with known toast positioning bug documented)
**Next Session**: Implement decision input workflow
**Backend Integration**: Ready (730/731 tests passing, all WebSocket handlers complete)
**Frontend Progress**: Phase F1 (70%) + Phase F2 (100%) = ~85% through Week 2 goals
