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.

**Developing Boids Simulation** I'm currently focused on the core boids behavior, specifically implementing separation, alignment, and cohesion following Reynolds' rules. I'm representing each boid as an oriented triangle to give them a clear direction. Next, I plan to work on smooth steering and mouse-cursor interaction, for fleeing behavior. **Refining Boid Implementation** I've been working on creating a single, self-contained HTML file. This involves using canvas for animation, and building a `Boid` class to store all the properties. The main loop is set up to update and draw the boids. I am currently fleshing out the math for separation, alignment, and cohesion behaviors, along with mouse avoidance. I'm also styling the visuals for a fullscreen black background and white boids, all within the constraints of the single file.

The flocking simulation is complete and contained in `index.html`. It uses a canvas element to render approximately 100 boids that follow Reynolds' rules (Separation, Alignment, Cohesion) and react to mouse movement by fleeing. You can open `index.html` in any modern web browser to view the simulation.
