Prompt for this run

Build a playable falling-block Tetris game on a canvas with a 10-column, 20-row visible board. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Include all seven tetrominoes with legal spawn positions. Use Left/Right to move, Up to rotate clockwise, Down to soft-drop, and Space to hard-drop. Show the controls. - Reject moves and rotations that overlap occupied cells or leave the board. Wall kicks are optional; if unsupported, reject the blocked rotation without changing the piece. - Lock landed pieces, clear complete rows, move rows above downward, and spawn the next piece. Display score, cleared-line count, level, and a next-piece preview. - Award 100, 300, 500, or 800 points for clearing one, two, three, or four rows with one piece, multiplied by the current level. Start at level 1 and increase gravity speed every ten cleared lines. - If a new piece cannot spawn, show Game Over. Provide Pause/Resume and Restart, with restart resetting the board, score, level, and piece sequence state. Hold and ghost pieces are optional. Verify: Move and rotate the first piece, then hard-drop it. Check that it locks into the board, a new piece spawns, and the next-piece preview advances. Pause and resume, then use Restart and check the cleared board, score, and level.

I'll create a complete Tetris game in a single HTML file with all the required functionality. Let me build this step by step.

I'll test the Tetris game to verify it works as required. Let me run and check it in the browser.

I can see the game is loading correctly. Let me test some of the core functionality by interacting with it.

Let me write a test script to validate core functionality and then check what's being rendered:

Let me try to create a better test by actually simulating the game behaviors. Let me review what I've implemented more carefully and make sure it functions as required. Looking at my implementation: 1. ✓ Game board with 10x20 grid 2. ✓ All 7 tetrominoes with proper shapes 3. ✓ Movement controls (Left/Right) 4. ✓ Rotation (Up arrow) 5. ✓ Soft drop (Down arrow) 6. ✓ Hard drop (Space) 7. ✓ Collision detection 8. ✓ Line clearing and scoring 9. ✓ Level progression 10. ✓ Game over detection 11. ✓ Pause/resume functionality 12. ✓ Restart functionality 13. ✓ Next piece preview The game appears to be loading correctly in the browser. Let's verify key components work:
