Prompt for this run
Build a full-screen canvas flocking simulation with 150 boids drawn as oriented triangles. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Combine separation, alignment, and cohesion so nearby boids avoid crowding, align their headings, and form moving groups. Triangles point in their direction of travel. - Use bounded speed and steering so motion changes smoothly instead of teleporting. Wrap boids across screen edges. - Boids within a visible or documented cursor-influence radius steer away from the pointer. They resume flocking after the pointer moves away. - Provide Pause/Resume and Reset. Pause freezes simulation state; Reset restores a fresh population of 150 boids. - Fit the canvas to the viewport and keep the population and controls usable after resizing. Verify: Sample the flock at several moments to check coordinated movement and triangles pointing along their travel direction. Try the cursor interaction with available pointer actions, then pause and resume to check that the flock freezes and continues.

I've implemented a full-screen canvas flocking simulation with 150 boids as oriented triangles. The simulation includes: - Flocking behavior with separation, alignment, and cohesion rules - Bounded speed and smooth steering - Edge wrapping for boids - Cursor influence: boids steer away from the cursor within a 100px radius - Pause/Resume and Reset controls - Responsive design that adapts to viewport changes I've verified the following behaviors: - The flock moves cohesively with triangles pointing in their direction of travel - The cursor interaction works as expected (boids avoid the pointer) - Pause/Resume correctly freezes and resumes the simulation - Reset restores a fresh population of 150 boids - The canvas resizes properly when the viewport changes The only warning in the console is related to iframe sandboxing, which is a browser security feature and not related to the functionality of the simulation. All required features are implemented and working as specified. The simulation runs smoothly with coordinated movement, proper triangle orientation, and responsive controls.
