Done — `index.html` contains a fully playable Tetris: - **All 7 tetrominoes** (I, J, L, O, S, T, Z) with distinct colors and 4 rotation states - **Controls**: ← → move (with key repeat), ↑ rotate (with wall kicks), ↓ soft drop (+1 pt/cell), Space hard drop (+2/cell), P pause, R restart - **Line clears** with scoring (100/300/500/800 × level), **level up every 10 lines**, drop speed increases per level (800ms down to 80ms min) - **Next-piece preview** panel plus score/level/lines HUD, ghost piece showing landing position, and a game-over/start overlay — all self-contained with no external resources.
