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.

I'll build a maze generator/solver visualization in a single self-contained `index.html`.

Now let me run it in the browser and inspect the initial output and console.

Generation is animating (carving visible in purple). Let me wait for it to finish and check the solver, then test "New Maze" during animation.

The maze solved with a path of 191 cells (190 steps), and the orange path clearly follows open passages from green Start to red Finish. The path crosses only open passages (visually confirmed — it never crosses a white wall). Now let me test "New Maze" while animation is active. I'll click New Maze, then quickly click it again during generation to verify cancellation works cleanly.

The click on "New Maze" didn't seem to register — the status still shows "Solved! Path length: 191 cells". The DOM text is unchanged. The click coordinates (449, 96) should be on the New Maze button. Let me check — the button is at around x=449, y=96 based on the screenshot. But the status didn't change. Maybe the click happened but the motion frames were captured after it already re-solved? No — the status still says "Solved! Path length: 191 cells (190 steps)" which is the OLD maze's result. If New Maze had been clicked, it would show "Generating maze…". Wait, actually looking more carefully — the click may have been registered but then... no. The status text is identical to before. Let me try clicking again and inspecting immediately.

The click still isn't registering — the status remains "Solved! Path length: 191 cells (190 steps)". The button is at approximately x=449, y=96 in the 1200×800 viewport. Looking at the screenshot, the "New Maze" button spans roughly x=405 to x=495, y=80 to y=112. So (449, 96) should be right in the middle of it. Maybe the click action needs the page to be reloaded first, or there's an issue with how the click is being dispatched. Let me try reloading and then clicking.
