Built `index.html` — single-file, offline maze visualizer: **Generation:** Recursive Backtracker (DFS stack) carving walls on `<canvas>`, seeded (reproducible), perfect maze with optional braided loops and paint-to-edit walls. **Solving:** Toggle **A*** (priority queue + Manhattan heuristic, `f=g+h`) vs **BFS** (queue). Animates *frontier* (yellow), *visited* (cyan), *current* (blue pulse) via `requestAnimationFrame` with adjustable speed, pause/step/instant. Path rendered as glowing orange spline with length stats, progress bar, and coverage %. **Interactions:** Size slider (7–41), random seed, animate-carving toggle, shuffle start/goal (Shift+click / Alt+click on canvas, drag to knock walls), keyboard `Space` solve/pause, `G` new maze. No external resources — all CSS/JS inline.

EVALUATION

1/5 broken

Maze canvas never renders any grid, walls, or solver animation despite full UI shell and JS errors present.

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.
