Generate a random maze with the recursive-backtracker algorithm on a canvas, then animate an A-star or BFS solver finding the path from start to finish.

The user wants me to create a single-page web app that:
1. Generates a random maze using the recursive backtracker algorithm
2. Displays it on a canvas
3. Animates a pathfinding algorithm (A* or BFS) solving the maze from start to finish

All in one self-contained `index.html` file with inline CSS and JS, no external resources.

Let me build this out with nice visuals and smooth animations.

The file is written. Let me verify it exists and looks good.

The maze app is ready at `/workspace/index.html`. Here's what it does: **Maze Generation** - Uses the **recursive backtracker** (iterative stack-based DFS) to carve a perfect maze — every cell is reachable, no loops - Walls are drawn as line segments per-cell on a canvas **Pathfinding Solvers** - **A*** — weighted by Manhattan distance heuristic, greedy + optimal - **BFS** — unweighted breadth-first guarantee **Animation** - Explored cells light up blue, frontier (open set) pulses orange, final path glows purple - Speed control: Slow → Medium → Fast → Instant (just shows the result) - Stats show nodes explored, path length, and timing after completion **Controls** | Button | Action | |---|---| | **Generate & Solve** | New maze + immediate solve | | **New Maze** | Just regenerate | | **Solve Only** | Re-run solver on current maze | | **Reset** | Clear solver visualization | You can also tweak the **width/height** (5–80 cols, 5–60 rows), pick **A* or BFS**, and adjust speed before solving.

TAKE IT TO CODE

EVALUATION

2/5 broken

Maze renders but solver never runs; requires clicking 'Generate & Solve' button which the probe never targeted, no animation or path shown.

MEASUREMENTS

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
