- TypeScript + Three.js client: character creator, Maple Court district, enterable venues (café, city hall, gym, store, arcade), build mode with 58-item furniture catalog, needs/mood systems, phone UI, day/night + weather, procedural audio
- Verified by two-client e2e protocol suite and headless-browser walkthrough
