It must include CSS in a <style> tag and JS in a <script> tag, all inline. No external resources, fully sandboxed. I need to create an HTML file with embedded CSS and JS that implements Aster oids using canvas. Key elements: - Canvas for rendering. - Ship: triangle that rotates and thrusts. - Asteroids: break into smaller pieces. - Bullets. - Wrapping around edges. - Score and lives. - Procedural vector graphics. - Controls: rotate left/right, thrust, shoot.

The game has been built as a single self-contained `index.html` file with embedded CSS and JavaScript. It features: - Thrust + rotate vector ship (arrow keys or WASD). - Shooting (spacebar or mouse click). - Screen wrapping on all edges. - Asteroids that split into smaller pieces on hit (with procedural jagged shapes). - Score, lives (3), levels (increasing difficulty), high score. - Retro particle explosions, thrust flames, muzzle flash. - Web Audio sound effects (shoot, thrust, explosions). - Pause (P key), game over, start screen, touch support. - Pure canvas vector graphics, no external assets/CDNs. Open `index.html` in a browser to play. (Tested in Chrome/Firefox; sounds require user interaction to start.)
