- 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.

Node's 'events' module doesn't work in browsers. Replaced with custom
Map-based implementation that provides the same API but works in both
Node.js and browser environments.
All 98 tests still pass.
