**Creating boids simulation** I need to create an index.html file that sets up a full-screen canvas for my boids simulation. I want the boids to have triangles oriented by their velocity, so they'll look sleek and dynamic. I'll implement smooth steering using flocking rules and a mouse flee force that has a falloff. I'll make sure to use requestAnimationFrame for smooth animations and adjust for resizing. Plus, I'm keeping it simple by using no external resources. Let's write the full code!

Created a full-screen boids flocking simulation in **`index.html`** (single self-contained file). It uses **separation, alignment, and cohesion** steering, renders each boid as an **oriented triangle** pointing along its velocity, and **flees from the mouse cursor smoothly**. Controls: - Press **F** to toggle flee - Press **R** to reset Open `index.html` in a browser to run it.

EVALUATION
Only a tiny cluster of triangle shapes visible in top-left corner; rest of full-screen canvas is empty black.

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.
