Done. `index.html` is a complete, self-contained 2048 game. Features: - **Arrow keys** (or WASD) to slide/merge tiles; **swipe** on touch devices - **Smooth animations**: tiles glide via CSS transforms, new tiles pop in, merges bump - **Score** tracking with a persisted **Best** score (localStorage) - **Win state** at 2048 and **Lose state** when no moves remain, both shown via an overlay with a restart button - Responsive layout with the classic 2048 color scheme Open it directly in any browser to play — no network or external assets needed.
