imutkarsht/Chess_analyzer ? reverse-engineered prompt

Build me a desktop chess analysis app that feels like a polished local alternative to Chess.com’s review tool.

I want to load a PGN file or paste PGN text, then click analyze and see every move evaluated with clear labels like best, good, mistake, blunder, and brilliant. The app should show a chessboard with drag and drop pieces, a move list, an evaluation graph, game history, and simple stats about the game. It should also support importing games from Chess.com and Lichess by username or game link, and let me browse multiple games inside one PGN.

Please make it store analysis and settings locally so it feels privacy friendly and loads faster next time. Add a settings screen for things like the engine path, API keys for optional AI summaries, board themes, piece themes, and sound options. A dark mode would be great too. Use current docs online if you need to, and make it feel clean, modern, and easy to use.
