Build a playable Tetris on a canvas with all seven tetrominoes, rotation, line clears, increasing speed, a next-piece preview, and score.

The user wants me to build a playable Tetris game as a single-page web app in one index.html file. Let me break down the requirements:

1. Canvas-based Tetris game
2. All seven tetrominoes (I, O, T, S, Z, J, L)
3. Rotation
4. Line clears
5. Increasing speed
6. Next-piece preview
7. Score tracking
8. All in one self-contained file with inline CSS and JS
9. No external resources

Let me create a complete Tetris game with all these features.

I'll build a complete Tetris game with all the requested features in a single index.html file.

I've created a complete Tetris game. Let me verify the file is there and check if there are any issues.

I've created a complete Tetris game in `/workspace/index.html`. Let me verify it works properly:

bash {"command":"cd /workspace && head -50 index.html && echo \"...\" && tail -20 index.html"}

The file looks good. Let me verify the file exists and is complete.

The Tetris game is complete. Here's what it includes: **Features:** - **All 7 tetrominoes**: I, J, L, O, S, T, Z shapes with distinct colors - **Rotation**: Up arrow rotates pieces with wall kick logic - **Line clears**: Detects and clears full lines, increments score - **Increasing speed**: Game speeds up as score increases (from 1000ms to min 50ms) - **Next-piece preview**: Shows the upcoming tetromino in a sidebar panel - **Score tracking**: Points for line clears with multiplier based on score - **Hard drop**: Space bar drops piece instantly - **Game over detection**: Shows overlay when no moves remain **Controls:** - ← → : Move left/right - ↓ : Soft drop - ↑ : Rotate - Space : Hard drop The game uses a 10×20 grid on a canvas with a responsive dark theme.
