- tavernLife.js: client-side NPCs (bartender, patrons, cat) with autonomous
movement, random speech bubbles, and real-player chat bubbles
- T2b: spectator camera — watch live dungeon runs from inside the tavern
(game list, spectate_start/update, ESC to leave)
- R1: sceneFromGameState adapter — converts dungeon game state to render-kit
Scene with lighting grid and entity mapping
- R2: pre-populated Kenney roguelikeSheet tile defaults for the tiled renderer
- Dungeon renderer support: TileRenderer + AsciiRenderer handle lightGrid,
dungeon features/items/monster entities
- 3 new tests (242 total, 36 suites, all passing)
