Sprint 2 rendering pipeline: tiles (#129), fog (#131), camera (#116). - tile_renderer.gd: programmatic TileSet with floor/wall/door/object placeholder tiles, renders from snapshot tile data - fog_renderer.gd: TileMapLayer overlay with three visibility states (visible/fog-edge/hidden), computed from visible_positions data - Camera2D: smoothing enabled (speed 6.0), 2x zoom, locked to player - game_state.gd: stores visible_tiles and visible_positions from snapshots - sim_bridge.gd: test data with 8x8 room, corridor, and Manhattan distance visibility for development without server - Scene render order: Tiles -> FogOverlay -> Entities - Background clear color set to near-black for unexplored areas Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
