Cal Corum e0c12467b0 CLAUDE: Improve UX with single-click OAuth, enhanced games list, and layout fix
Frontend UX improvements:
- Single-click Discord OAuth from home page (no intermediate /auth page)
- Auto-redirect authenticated users from home to /games
- Fixed Nuxt layout system - app.vue now wraps NuxtPage with NuxtLayout
- Games page now has proper card container with shadow/border styling
- Layout header includes working logout with API cookie clearing

Games list enhancements:
- Display team names (lname) instead of just team IDs
- Show current score for each team
- Show inning indicator (Top/Bot X) for active games
- Responsive header with wrapped buttons on mobile

Backend improvements:
- Added team caching to SbaApiClient (1-hour TTL)
- Enhanced GameListItem with team names, scores, inning data
- Games endpoint now enriches response with SBA API team data

Docker optimizations:
- Optimized Dockerfile using --chown flag on COPY (faster than chown -R)

# 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`
### 1. Explicit Store Imports Required
All Pinia stores MUST be explicitly imported:
```typescript
// WRONG - will cause "useAuthStore is not defined":
const authStore = useAuthStore()
// CORRECT:
import { useAuthStore } from '~/store/auth'
const authStore = useAuthStore()
```
### 2. No `app/` Directory Allowed
**CRITICAL**: Do NOT create an `app/` directory in the frontend root. Nuxt 4 treats this as a special directory that overrides `app.vue`. If NuxtWelcome appears instead of your app, delete `app/` and rebuild.

## Development
```bash
npm install # First time
npm run dev # Dev server at http://localhost:3000
npm run type-check # Check types
npm run lint # Lint code
```
## Configuration
### Environment Variables
Copy `.env.example` to `.env` and configure:
```bash
# API endpoints
NUXT_PUBLIC_API_URL=http://localhost:8000
NUXT_PUBLIC_WS_URL=http://localhost:8000
# Discord OAuth (public client ID - safe to expose)
NUXT_PUBLIC_DISCORD_CLIENT_ID=your-client-id
NUXT_PUBLIC_DISCORD_REDIRECT_URI=http://localhost:3000/auth/callback
# Vite dev server allowed hosts (comma-separated)
# Add your domain for external access
NUXT_ALLOWED_HOSTS=localhost,127.0.0.1
```
**Note**: `NUXT_ALLOWED_HOSTS` is read in `nuxt.config.ts` to configure Vite's `allowedHosts`. Required when accessing dev server through a reverse proxy or external domain.
### 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`
