Create a full-screen flocking simulation of boids using separation, alignment, and cohesion, drawn as oriented triangles that steer smoothly and flee from the mouse cursor.
thinking
The user wants a full-screen flocking simulation (boids) with: 1. Separation, alignment, and cohesion behaviors 2. Boids drawn as oriented triangles 3. Smooth steering 4. Flee from mouse cursor 5. Single self-contained HTML file with inline CSS and JS 6. No external resources Let me create this. I'll implement a complete boids simulation with canvas rendering.

The file has been written successfully. Let me verify it's in place and looks correct.
The boids flocking simulation is complete at `/tmp/ws/index.html`. Here's what it implements: - **Separation** — boids steer away from neighbours within a close range to avoid crowding - **Alignment** — boids match the average heading of nearby flockmates - **Cohesion** — boids steer toward the centre of mass of their neighbours - **Mouse flee** — boids within 180px of the cursor flee from it with proportional force - **Click burst** — clicking the canvas delivers a strong outward kick to nearby boids - **Screen wrapping** — boids wrap around edges with a gentle turning margin - **Smooth steering** — velocity uses inertia (0.92) so turns are gradual and organic - **Oriented triangles** — each boid is a small triangle that smoothly rotates toward its heading - **Trail effect** — a semi-transparent overlay per frame creates motion trails - **Per-boid colour** — slight HSLA variation in the blue-cyan range with randomised alpha No external resources, no CDNs — fully self-contained in one file. Just open `index.html` in a browser.

RUN
EVALUATION
Boid-like flocking with fish/streak shapes flows continuously and reacts to click, drag, and wheel with visible scattering.

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.
