Prompt for this run
Build a maze generator and solver visualization on a canvas. 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: - Generate a 25 by 15 cell rectangular maze using randomized recursive backtracking. All cells must be reachable, with exactly one simple path between any pair of cells. - Use the upper-left cell as Start and lower-right as Finish. Draw cell walls clearly and animate generation so carving progress is visible. - After generation finishes, animate either BFS or A-star exploring the maze, then highlight the complete path from Start to Finish. The path must cross only open passages. - Provide New Maze and Replay Solver. New Maze cancels the previous animation and generates a fresh maze; Replay Solver uses the existing maze without changing its walls. - Mark start, finish, exploration, and solution with distinguishable styles and a short legend. Verify: Inspect maze-carving progress and request New Maze while animation is active. Check that the new generation replaces the previous view cleanly. If the solver starts during inspection, check that its visible steps follow open passages.

thinking
Built `index.html` — a self-contained maze generator/solver visualization (no external resources). **Features:** - 25×15 maze generated with randomized recursive backtracking (iterative stack), producing a perfect maze — all cells reachable with exactly one path between any pair - Animated carving with a highlighted current cell, then automatic solving - A* (Manhattan) or BFS solver selectable, with animated exploration/frontier, then an animated gold solution path that only crosses open passages - Start (upper-left, green "S") and Finish (lower-right, red "F"), plus distinguishable carved/explored/frontier/solution styles and a legend - **New Maze** cancels any in-flight animation via token + `cancelAnimationFrame` and cleanly restarts; **Replay Solver** re-runs on the same walls (disabled until generation completes) - Speed slider, live status, and stats (cells carved, cells explored, path length) **Verified in browser:** - Generation progress visibly carving (counter incrementing, e.g. 137/375) - Clicked **New Maze** mid-generation — previous view replaced cleanly and carving restarted from scratch - Solver completed: 375/375 cells reachable, A* solved in 94 steps with 111 cells explored; visible path follows open passages only - **Replay Solver** cleared exploration and re-solved the identical maze **Unverified:** BFS mode was implemented with the same passage-checking logic but not run separately in the browser; long-session/repeated-cancel stress beyond the single mid-animation New Maze test was not exercised.
