Build a playable 2048 game with arrow-key tile sliding and merging, smooth animations, a score, and win and lose states.

The user wants a complete 2048 game as a single HTML file with all CSS and JS inline. No external resources allowed. I need to create a self-contained single-page web app.

Key requirements:
- Playable 2048 game
- Arrow-key tile sliding and merging
- Smooth animations
- Score display
- Win state (2048 tile)
- Lose state (no moves left)

I'll structure this as:
1. HTML structure with game board and score display
2. CSS for styling and animations
3. JavaScript for game logic, event handling, and rendering

The game logic should:
- Track the 4x4 grid state
- Handle arrow key events
- Move tiles in the specified direction
- Merge adjacent tiles with same values
- Spawn new tiles (usually 2s) after moves
- Track score (sum of merged tiles)
- Detect win (2048 tile appears) and lose (no moves possible) states
- Use CSS transitions for smooth animations

Let me create a comprehensive implementation. I'll use a clean, modern approach with:
- Grid layout using CSS grid
- Tile objects with position and value
- Animation using CSS transitions
- Event listeners for keyboard input
- Game state management

I'll write the entire thing to index.html in one go.

I'll create a complete, self-contained 2048 game as a single HTML file with inline CSS and JavaScript. Here it is:

★★★★★ 1/5 broken

2048 UI shows but the game board never renders any tiles and arrow/WASD input has no visible effect.
