Frontend alignment with backend WebSocket protocol: **Type System Fixes**: - types/game.ts: Changed DecisionPhase to use 'awaiting_*' convention matching backend - types/game.ts: Fixed PlayOutcome enum values to match backend string values (e.g., 'strikeout' not 'STRIKEOUT') - types/game.ts: Added comprehensive play outcome types (groundball_a/b/c, flyout variants, x_check) **Decision Detection**: - store/game.ts: Updated decision detection to check both decision prompt AND gameState.decision_phase - components: Updated all decision phase checks to use 'awaiting_defensive', 'awaiting_offensive', 'awaiting_stolen_base' **WebSocket Enhancements**: - useWebSocket.ts: Added game_joined event handler with success toast - useWebSocket.ts: Fixed dice roll data - now receives d6_two_a and d6_two_b from server - useWebSocket.ts: Request fresh game state after decision submissions to sync decision_phase **New Constants**: - constants/outcomes.ts: Created centralized PlayOutcome enum with display labels and descriptions **Testing**: - Updated test expectations for new decision phase naming - All component tests passing **Why**: Eliminates confusion from dual naming conventions. Frontend now uses same vocabulary as backend. Fixes runtime type errors from enum value mismatches. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Frontend SBA - Strat-O-Matic Baseball Association Web App
Overview
Vue 3 + Nuxt 3 frontend for the SBA league. Real-time game interface with WebSocket communication to backend.
Tech Stack: Nuxt 4.1.3, TypeScript (strict), Tailwind CSS, Pinia, Socket.io-client, Discord OAuth
CRITICAL: Nuxt 4 Breaking Changes
MUST READ: .claude/NUXT4_BREAKING_CHANGES.md
All Pinia stores MUST be explicitly imported:
// WRONG - will cause "useAuthStore is not defined":
const authStore = useAuthStore()
// CORRECT:
import { useAuthStore } from '~/store/auth'
const authStore = useAuthStore()

League Theme
- Primary: #1e40af (SBA Blue)
- Secondary: #dc2626 (SBA Red)
Mobile-First Design
- Breakpoints: xs(375px), sm(640px), md(768px), lg(1024px)
- Touch-friendly: 44x44px minimum buttons
- Sticky scoreboard, bottom sheets for inputs
Key Architecture Concepts
Data Resolution Pattern
Game state contains minimal LineupPlayerState (lineup_id, position). Use gameStore.findPlayerInLineup(lineupId) to get full player data (name, headshot).
Team Determination
- Top of inning: away bats, home fields
- Bottom of inning: home bats, away fields
- Use
gameStore.battingTeamId/gameStore.fieldingTeamId
