The user wants me to build a Space Invaders game as a single self-contained HTML file. Let me plan out the components: 1. **Canvas setup**: Create a canvas element for rendering 2. **Player cannon**: A ship that can move left/right and shoot bullets 3. **Alien grid**: Multiple rows of aliens that: - Move horizontally, then drop down when hitting edges - Get faster as they're destroyed - Can shoot back at the player 4. **Bunkers**: Destructible barriers that get damaged by bullets 5. **Score system**: Points for destroying aliens 6. **Lives system**: Player has multiple lives 7. **Game states**: Start screen, playing, game over, win Let me write this as a complete single HTML file with all CSS and JS inline.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
