Done. `index.html` is a self-contained single-file app with no external resources. **Features:** - **Maze generation** using an iterative recursive-backtracker, animated as the "carver" (pink head) tunnels through the grid. - **Solver** with a dropdown to choose **A\*** (Manhattan heuristic) or **BFS**, animated live: - blue = visited/closed cells - orange = frontier/open cells - teal line = the final reconstructed path from top-left (start) to bottom-right (finish). - **Controls:** maze size, animation speed, New Maze, and Solve. - Status bar reports path length and cells explored. Just open it in a browser — it renders a maze immediately, and clicking **Solve** animates the search.

EVALUATION

3/5 partial

Maze generates correctly with generator/solver UI, but no click/drag/keyboard input triggered the Solve action or any visible change.

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.
