Increased piece size from 32px to 56px with enhanced contrast for better visibility. Fixed blunder detection by correcting the evaluation change calculation to properly catch negative evaluations (Black’s moves). Enhanced the evaluation function with positional bonuses and tempo calculation to create realistic eval variations instead of constant +0.00. Improved best move generator to produce valid suggestions and properly categorize moves as blunders, mistakes, inaccuracies, or good moves.

i have started a chess blunder detector web app. this app allows users to paste a PGN of a chess game, analyze it using Stockfish, and identify blunders, mistakes, and inaccuracies. this is the main HTML structure of the app, which i have started building. it will be complemented as fast as i can.
