- Fix input_mapper double-check bug (redundant InputEventKey + pressed filter)
- Add bounds checking for position arrays in entity_renderer and game_state
- Make test snapshot deterministic (incrementing counter, not wall clock)
- Fix tween overlap in monologue_display (cancel active tween before new one)
- Extract TILE_SIZE constant from magic number 32
- Add 5 D-030 Layer 1 fixture tests for snapshot parsing (7/7 total passing)
