✨ Features

Category filter tabs — filter by Core / AI & ML / CS & Systems / Research & Mind / Extras
Reading Road — 11-phase learning roadmap from meta-learning to research synthesis
Search — chapter-level search across all 58 books
Seven Doors Method — each concept taught through story, metaphor, sacred analogue, and recall challenge
Bilingual — Bengali primary, English secondary throughout
Progressive unlocking — chapters unlock sequentially with XP and rank progression
Cheat sheets — collect one-line secrets from each chapter
Live Python — DSA book includes Pyodide-powered code execution
Zero dependencies — pure HTML/CSS/JS, no build step, no frameworks

🏗️ Architecture

Each book is a self-contained multi-file project:

book-folder/
├── index.html      ← Structure & screens
├── style.css       ← All styling
├── engine.js       ← Game logic: XP, ranks, particles, sound, save/load
├── doors-1-N.js    ← Story content (split for atomic writes)
└── doors-N-M.js    ← More story content

The root index.html is the hub — the courtyard with filter tabs that connects all 58 books.

📖 Pedagogy — the Seven Doors Method

Each chapter teaches one concept through 11 moves that make it permanent:

Embody, don't define — concepts shown through story, not listed
Isomorphic metaphor — each concept maps to a physical analogy
Sacred analogue — Islamic/cultural connections that are structurally isomorphic
Teacher as person — named characters with physical signatures
Failure-first — show the wrong way before the right way
Sensory immersion — smell, sound, touch, not just sight
Compress to one line — each chapter ends with a memorable secret
Cross-door synthesis — later chapters reference earlier teachers
Recall challenge — bilingual Q&A to test retention
Senior lesson — concrete, actionable next step
Spirit word — a single Arabic/Bengali concept anchoring the lesson
