The user wants me to create a flocking simulation (boids) in a single HTML file. I need to implement: 1. Boids as oriented triangles 2. Three flocking rules: separation, alignment, cohesion 3. Fleeing behavior from mouse cursor 4. Smooth steering 5. Full-screen canvas Let me create a complete, self-contained index.html file with all the CSS and JavaScript inline.

I've created a complete boids flocking simulation in a single HTML file. Let me verify it was written correctly.
Done! Created `index.html` with a complete boids flocking simulation featuring: - **200 boids** rendered as oriented triangles - **Three flocking behaviors:** - **Separation** - steers away from nearby boids - **Alignment** - steers toward average heading of neighbors - **Cohesion** - steers toward center of mass of neighbors - **Mouse flee behavior** - boids scatter when cursor approaches - **Smooth steering** with force limiting for natural movement - **Visual effects:** - Color shifts based on speed (cyan to yellow) - Subtle glow effect - Motion trails from fade-clear rendering - **Edge wrapping** - boids reappear on opposite side - **Touch support** for mobile devices Open `index.html` in a browser to see the simulation. Move your mouse to scatter the flock!
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
Boids flock and swirl continuously as oriented triangles, with visible reaction to mouse near cursor (fleeing curve shape).

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.
