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.

Built a complete playable Tetris game in a single self-contained `index.html` (no external assets/CDNs): - **Board & pieces:** 10×20 canvas board, all seven tetrominoes (I/O/T/S/Z/J/L) via a 7-bag randomizer with legal centered spawns, collision-rejected moves/rotations (with simple wall kicks; blocked rotations leave the piece unchanged). - **Controls (shown on page):** ←/→ move, ↑ rotate clockwise, ↓ soft-drop, Space hard-drop, plus P pause and R restart, and on-screen buttons. Ghost piece included. - **Gameplay:** Landed pieces lock, full rows clear and rows above drop, next piece spawns. Score/lines/level display and a next-piece preview canvas are included. Scoring is 100/300/500/800 × current level for 1–4 lines; level starts at 1 and rises every 10 lines with faster gravity. Game Over shows when a spawn is blocked; Pause/Resume and Restart (full reset of board, score, level, and bag state) are provided. **Verified in the browser:** - Moved the first piece left, pressed rotate, then hard-dropped with Space — the piece locked at the bottom, a new piece (the former preview) spawned, and the next-piece preview advanced. - Pause showed the PAUSED overlay and "Paused" status; Resume restored play. - Restart cleared the locked blocks and reset score/lines/level to 0/0/1 with a fresh piece spawning. - No console errors (only the sandbox iframe warning from the harness). **Unverified:** Line-clear scoring at higher levels and the Game Over path were not played through to completion in the browser (they'd require many drops); the rotate key was exercised on an O piece, so a visible non-O rotation change wasn't observed, though the rotation/collision logic is in place.
