Flocking simulation written to `index.html` — single self-contained file, no external resources. **Features:** - 120 boids (20–220 slider) as velocity-oriented triangles with heading-colored bloom - Full Reynolds flocking: **Separation / Alignment / Cohesion** with independent weights, perception radius, and separation distance sliders - **Smooth steering:** acceleration integration, speed limiting, `maxForce` (agility) capping per behavior, toroidal neighbor distance - **Mouse predator:** cursor projects a radial "flee" field (tunable flee strength + radius); boids apply exponential evasion force — move to scatter, click to burst new boids outward - Wrap / bounce edges, motion-trail fade, neighbor-link overlay, scatter/add/reset controls - Keyboard: `Space` pause, `R` reset, `S` scatter
