- Created Renderer class with tile rendering, selection highlighting, and fade-in animations
- Created GridManager class with tile array and selection state management (blocking dependency)
- Added tilesSelected event to GameEvents interface
- Created comprehensive test suite for Renderer with 9 test cases
**Renderer Features:**
- Renders all non-cleared tiles from GridManager at correct positions
- Centers grid horizontally and vertically within canvas
- Displays emoji characters centered within tile bounds
- Selection highlights with border (3px) and background tint (30% opacity)
- Fade-in animation over ~100ms using performance.now()
- Uses CONFIG.tile.size, gap, cornerRadius for positioning
- Respects CONFIG.colors for styling
**GridManager Features:**
- Manages 2D tile array (10x16 grid = 160 tiles)
- Selection state tracking with toggle behavior (0-2 tiles)
- selectTile() with toggle deselect and cleared tile filtering
- Emits tilesSelected event when 2 tiles selected
- getTileAt() for coordinate-based tile access
**Note:** Tests created but not runnable due to sandbox file system restrictions
preventing npm install. Implementation verified manually against plan requirements.
