ChessLeak is a premium, client-side Chess Analysis & Leak Detection web application designed to help chess players identify and fix recurring weaknesses in their games. By scanning games or parsing custom PGN (Portable Game Notation) files, it pinpoints exactly where you lose material, panic under time pressure, or deviate from optimal opening play.

Designed with a high-fidelity, glassmorphic dark interface, ChessLeak offers a seamless offline analysis dashboard and an interactive "Antidote Trainer" to practice your critical positions.

• 📊 Leak Score Dashboard: Get an instant "Leak Rating" based on overall blunders, time management, and tactical slip-ups.
• ⏱️ Time Management Heatmap: Visualize how your move quality degrades as the clock ticks down, identifying your "Panic Zones".
• 📖 Repertoire Auditor: Analyze opening performance, showing exact moves where you lose the advantage or fall into common traps.
• 🧩 Interactive Leak Trainer: Load your own blunders onto an interactive chessboard and find the "Antidote Move" (the best continuation) to rebuild muscle memory.
• ⚡ 100% Offline & Client-Side: No servers, no sign-ups. Your PGNs and usernames are processed entirely within the browser.

Since ChessLeak is a pure client-side application built with modern HTML5, CSS3, and Vanilla JavaScript, running it is simple:

   # Using Python
   python3 -m http.server 8000
   
   # Using Node.js
   npx serve .

2. Open http://localhost:8000 in your web browser.
