**Problem:**
- player-ownership.ts imported drizzle-orm and @/db at top level
- When RoomMemoryPairsProvider imported client-safe utilities, Webpack bundled ALL imports including database code
- This caused hydration error: "The 'original' argument must be of type Function"
- Node.js util.promisify was being called in browser context
**Solution:**
1. Created player-ownership.client.ts with ONLY client-safe utilities
- No database imports
- Safe to import from 'use client' components
- Contains: buildPlayerOwnershipFromRoomData(), buildPlayerMetadata(), helper functions
2. Updated player-ownership.ts to re-export client utilities and add server-only functions
- Re-exports everything from .client.ts
- Adds buildPlayerOwnershipMap() (async, database-backed)
- Safe to import from server components/API routes
3. Updated RoomMemoryPairsProvider to import from .client.ts
**Result:**
- No more hydration errors on /arcade/room
- Client bundle doesn't include database code
- Server code can still use both client and server utilities

Replace direct NODE_ENV assignments with Object.defineProperty
to avoid "Cannot assign to read-only property" TypeScript errors.
This allows tests to safely override the readonly NODE_ENV
environment variable for testing different environments.
Fixes 4 TS2540 errors.

Run Biome formatter on all files to ensure consistent code style:
- Single quotes for JS/TS
- Double quotes for JSX
- 2-space indentation
- 100 character line width
- Semicolons as needed
- ES5 trailing commas
This is the result of running: npx @biomejs/biome format . --write
