Jimmyu2foru18/A-Pathfinding-Algorithm — reverse-engineered prompt

Build me a simple interactive learning site that teaches the A* pathfinding algorithm. I want it to feel like a hands on guide, not just a wall of text. The main page should explain what A* is, why it is useful, and guide people through beginner topics like graphs, search algorithms, heuristics, open and closed sets, path reconstruction, performance, and real world uses like games, robotics, and logistics.

Please include an interactive demo where someone can click on a grid to set the start point, end point, and obstacles, then watch the algorithm run step by step. Show the explored nodes, the final path, and let users compare different heuristics. Keep it in plain JavaScript, HTML, and CSS so it can run as a static site.

Also add clear learning sections, a demo guide, FAQ, glossary, checklist, references, and a developer focused implementation explanation. Make it beginner friendly but still useful for programmers who want working A* code.
