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.

**Planning index implementation**

I need to create the index and inspect the current working directory. It seems like I should implement it in a polished way, perhaps using a full-screen canvas for a better view. I'll consider adding controls and maybe a title too. It's important to keep everything internal, avoiding any external dependencies. I really need to focus on writing this smoothly and effectively! Let's get started on the implementation!
bash {"command":"pwd && ls -la"}

Created `/tmp/ws/index.html` with a self-contained full-screen boids flocking simulation featuring: - Separation, alignment, and cohesion behaviors - Smooth steering and screen wrapping - Mouse cursor flee behavior with visual influence radius - Oriented glowing triangle boids - Adjustable population, flock influence, and drift - Pause/resume controls - Live particle count and FPS display - Responsive UI with no external resources or network requests

EVALUATION

4/5 working

Boids flock into circular clusters with glowing triangles, mouse hover shows flee/repulsion glow, animates continuously.

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.
