docs: Rewrite README as landing-page-structured guide

Restructure README.md using the PAS (Problem-Agitate-Solution) copywriting framework to better convert visitors into users. Adds badge row, benefit-driven headline, problem/solution narrative, social proof, FAQ, and multiple CTAs. All original technical content preserved in collapsible <details> sections. Original README saved as README.backup.md.

-> A visual, example-driven guide to Claude Code — from basic concepts to advanced agents, with copy-paste templates that bring immediate value.
+# Master Claude Code in a Weekend

-## Why This Guide?
+Go from typing `claude` to orchestrating agents, hooks, skills, and MCP servers — with visual tutorials, copy-paste templates, and a guided learning path.

-This project complements [Anthropic's official documentation](https://code.claude.com/docs/en/overview) with a different approach:
+**[Get Started in 15 Minutes](#-get-started-in-15-minutes)** | **[Find Your Level](#-not-sure-where-to-start)** | **[Browse the Feature Catalog](CATALOG.md)**
+
+---
+
+## The Problem
+
+You installed Claude Code. You ran a few prompts. Now what?
+
+- **The official docs describe features — but don't show you how to combine them.** You know slash commands exist, but not how to chain them with hooks, memory, and subagents into a workflow that actually saves hours.
+- **There's no clear learning path.** Should you learn MCP before hooks? Skills before subagents? You end up skimming everything and mastering nothing.
+- **Examples are too basic.** A "hello world" slash command doesn't help you build a production code review pipeline that uses memory, delegates to specialized agents, and runs security scans automatically.
+
+You're leaving 90% of Claude Code's power on the table — and you don't know what you don't know.
+
+---
+
+## How Claude How To Fixes This
+
+This isn't another feature reference. It's a **structured, visual, example-driven guide** that teaches you to use every Claude Code feature with real-world templates you can copy into your project today.

 | | Official Docs | This Guide |
 |--|---------------|------------|
-| **Format** | Reference documentation | Visual tutorials with diagrams |
+| **Format** | Reference documentation | Visual tutorials with Mermaid diagrams |
 | **Depth** | Feature descriptions | How it works under the hood |
-| **Examples** | Basic snippets | Production-ready templates you can use immediately |
-| **Structure** | Feature-organized | Progressive learning path (beginner → advanced) |
+| **Examples** | Basic snippets | Production-ready templates you use immediately |

-| **Self-Assessment** | None | Interactive quizzes to identify skill gaps and build a personalized learning path |
+| **Self-Assessment** | None | Interactive quizzes to find your gaps and build a personalized path |

-**What you'll find here:**
- Mermaid diagrams explaining how each feature works
- Ready-to-use configurations you can copy into your project
- Real-world examples with context and best practices
- Clear progression from `/help` to building custom agents
- Troubleshooting guides based on common issues
+### What you get:
+
+- **10 tutorial modules** covering every Claude Code feature — from slash commands to custom agent teams
+- **Copy-paste configs** — slash commands, CLAUDE.md templates, hook scripts, MCP configs, subagent definitions, and full plugin bundles
+- **Mermaid diagrams** showing how each feature works internally, so you understand *why*, not just *how*
+- **A guided learning path** that takes you from beginner to power user in 11-13 hours
+- **Built-in self-assessment** — run `/self-assessment` or `/lesson-quiz hooks` directly in Claude Code to identify gaps

+### 1. Find your level
+
+Take the [self-assessment quiz](LEARNING-ROADMAP.md#-find-your-level) or run `/self-assessment` in Claude Code. Get a personalized roadmap based on what you already know.
+
+### 2. Follow the guided path
+
+Work through 10 modules in order — each builds on the last. Copy templates directly into your project as you learn.
+
+### 3. Combine features into workflows
+
+The real power is in combining features. Learn to wire slash commands + memory + subagents + hooks into automated pipelines that handle code reviews, deployments, and documentation generation.
+
+### 4. Test your understanding
+
+Run `/lesson-quiz [topic]` after each module. The quiz pinpoints what you missed so you can fill gaps fast.

+## FAQ
+
+**Is this free?**
+Yes. MIT licensed, free forever. Use it in personal projects, at work, in your team — no restrictions beyond including the license notice.
+
+**Is this maintained?**
+Actively. The guide is synced with every Claude Code release. Current version: v2.1.1 (March 2026), compatible with Claude Code 2.1+.
+
+**How is this different from the official docs?**
+The official docs are a feature reference. This guide is a tutorial with diagrams, production-ready templates, and a progressive learning path. They complement each other — start here to learn, reference the docs when you need specifics.
+
+**How long does it take to go through everything?**
+11-13 hours for the full path. But you'll get immediate value in 15 minutes — just copy a slash command template and try it.
+
+**Can I use this with Claude Sonnet / Haiku / Opus?**
+Yes. All templates work with Claude Sonnet 4.6, Claude Opus 4.6, and Claude Haiku 4.5.
+
+**Can I contribute?**
+Absolutely. See [CONTRIBUTING.md](CONTRIBUTING.md) for guidelines. We welcome new examples, bug fixes, documentation improvements, and community templates.
+
+**Can I read this offline?**
+Yes. Run `uv run scripts/build_epub.py` to generate an EPUB ebook with all content and rendered diagrams.

-### Planning Mode
-
-Create detailed implementation plans before coding:
-```
-User: /plan Implement user authentication system
-
-Claude: [Creates comprehensive step-by-step plan]
-
-User: Approve and proceed
-```
-
-**Benefits**: Clear roadmap, time estimates, risk assessment
-
-### Extended Thinking
-
-Deep reasoning for complex problems. Toggle with `Alt+T` / `Option+T`, or set `MAX_THINKING_TOKENS` environment variable:
-```bash
-# Toggle in-session: press Alt+T (Option+T on macOS)
-
-# Or set via environment variable
-MAX_THINKING_TOKENS=10000 claude
-
-# Then ask complex questions
-User: Should we use microservices or monolith?
-Claude: [Analyzes trade-offs systematically with extended reasoning]
-```
-
-**Benefits**: Better architectural decisions, thorough analysis
-
-### Background Tasks
-
-Run long operations without blocking:
-```
-User: Run tests in background
-
-Claude: Started bg-1234, you can continue working
-
-[Later] Test results: 245 passed, 3 failed
-```
-
-**Benefits**: Parallel development, no waiting
-
-### Permission Modes
-
-Control what Claude can do:
- **`default`**: Standard permissions with confirmation prompts
- **`acceptEdits`**: Auto-accept file edits, confirm other actions
- **`plan`**: Analysis and planning only, no modifications
- **`dontAsk`**: Accept all actions without confirmation
- **`bypassPermissions`**: Skip all permission checks (dangerous)
-
-```bash
-claude --permission-mode plan          # Code review mode
-claude --permission-mode acceptEdits   # Learning mode
-claude --permission-mode default       # Standard mode
-```
-
-### Headless Mode
-
-Run Claude Code in CI/CD and automation:
-```bash
-claude -p "Run tests and generate report"
-```
-
-**Use Cases**: CI/CD, automated reviews, batch processing
-
-### Session Management
-
-Manage multiple work sessions:
-```bash
-/resume                          # Resume a previous session interactively
-/rename                          # Rename the current session
-/fork                            # Fork the current session
-claude -c                        # Continue the most recent session
-claude -r "session"              # Resume a session matching the query
-```
-
-### Interactive Features
-
-**Keyboard Shortcuts**: Ctrl+R (search), Tab (complete), ↑/↓ (history)
-
-**Command History**: Access previous commands
-
-**Multi-line Input**: Complex prompts across multiple lines
-
-### Configuration
-
-Customize Claude Code behavior in `~/.claude/settings.json`:
-```json
-{
-  "permissions": {
-    "allow": ["Read", "Glob", "Grep", "Bash(git *)"],
-    "deny": ["Bash(rm -rf *)"]
-  },
-  "hooks": {
-    "PreToolUse": [{
-      "matcher": "Write",
-      "hooks": ["~/.claude/hooks/format-code.sh"]
-    }]
-  },
-  "env": {
-    "MAX_THINKING_TOKENS": "10000"
-  }
-}
