+# Next.js Migration Status
+
+## Overview
+Migrating 97harsh.github.io from Jekyll to Next.js 14.x with a stability-first architecture optimized for minimal ongoing maintenance.
+
+**Branch**: `nextjs-migration`
+**Plan Document**: [valiant-exploring-summit.md](/Users/harsh/.claude/plans/valiant-exploring-summit.md)
+
+---
+
+## ✅ Phase 1: Foundation Setup (COMPLETED)
+
+**Status**: ✅ Complete
+**Commit**: `833893c`
+**Completed**: 2025-12-28
+
+### What Was Built
+
+1. **Next.js 14.x Setup**
+   - Pages Router (NOT App Router for stability)
+   - TypeScript configuration
+   - Static export configuration for GitHub Pages
+   - URL redirects (/:year/:month/:day/:slug → /posts/:slug)
+
+2. **Project Structure**
+   ```
+   nextjs-site/
+   ├── components/      # React components
+   ├── contexts/        # State management
+   ├── pages/           # Routes
+   ├── styles/          # CSS files
+   ├── content/posts/   # Markdown (ready for migration)
+   ├── lib/             # Utilities (to be created)
+   └── public/          # Static assets
+   ```
+
+3. **Core Components Created**
+   - **FontContext.tsx**: Font preference management (30 lines vs 428 lines vanilla JS)
+   - **Layout.tsx**: Page wrapper with Head management
+   - **Sidebar.tsx**: Navigation sidebar (converted from Liquid template)
+   - **WelcomeModal.tsx**: First-visit font selection modal
+   - **_app.tsx**: App wrapper with FontProvider
+   - **_document.tsx**: HTML document structure
+
+4. **Styling**
+   - ✅ Preserved all existing CSS (poole.css, hyde.css, custom.css, syntax.css)
+   - ✅ Added globals.css for font classes
+   - ✅ Font loading (PT Sans, Abril Fatface, OpenDyslexic)
+   - ✅ Font Awesome icons
+
+5. **Assets**
+   - ✅ Copied all images to public/assets/
+   - ✅ Copied JSON data files
+
+### Features Working
+
+- ✅ Font toggle system (Default ↔ OpenDyslexic)
+- ✅ Welcome modal appears on first visit
+- ✅ Font preference persisted in localStorage
+- ✅ Sidebar navigation structure
+- ✅ Responsive design maintained
+- ✅ Hydration-safe implementation (no SSR issues)
+- ✅ Type-safe with TypeScript
+
+### Dependencies (8 Total)
+
+**Core:**
+- next@14.0.4 (exact version pinned)
+- react@18.2.0
+- react-dom@18.2.0
+- gray-matter@^4.0.3 (frontmatter parsing)
+- remark@^15.0.1 (markdown processing)
+- remark-html@^16.0.1
+- date-fns@^3.0.0
+
+**Dev:**
+- typescript@^5.3.3
+- eslint@^8.56.0
+- eslint-config-next@14.0.4
+
+### Testing Needed
+
+⚠️ **Note**: Dependencies are installed but dev server not tested yet due to Node.js icu4c library issue on local machine. Will need to:
+
+1. Fix Node.js installation or use different environment
+2. Run `npm install` in `nextjs-site/`
+3. Run `npm run dev` to test development server
+4. Verify font toggle functionality
+5. Verify welcome modal appears and works correctly
+

+
+## 🚧 Phase 2: Content Migration (IN PROGRESS)
+
+**Status**: Not started

+
+## How to Test Locally
+
+```bash
+cd nextjs-site
+
+# Install dependencies
+npm install
+
+# Start development server
+npm run dev
+# Open http://localhost:3000
+
+# Type check
+npm run type-check
+
+# Lint
+npm run lint
+
+# Build for production
+npm run build
+
+# Full validation
+npm run validate
+```
+
+---
+
+## Next Steps
+
+1. **Immediate**: Fix Node.js environment to test dev server
+   - Install/update icu4c library
+   - OR test in different environment (Docker, CI, another machine)
+
+2. **Phase 2**: Start content migration
+   - Copy markdown files to `content/posts/`
+   - Implement `lib/posts.ts`
+   - Create post pages with dynamic routing
+
+3. **Documentation**: Update README with test results once dev server is verified
+
+---
+
+## Key Decisions Made
+
+1. **Pages Router over App Router**: For 5+ years of stability
+2. **Static Export**: For GitHub Pages compatibility, no server needed
+3. **Minimal Dependencies**: Only 8 packages to reduce maintenance
+4. **Keep Existing CSS**: Zero risk CSS migration strategy
+5. **React Context**: No Redux/Zustand needed for simple font state
+6. **TypeScript**: Catch errors at build time
+7. **Exact Version Pinning**: Prevent surprise breaking changes
+
+---

+## Timeline
+
+- **Week 1** (Current): Foundation ✅
+- **Week 2**: Content Migration 🚧
+- **Week 3**: Features 📋
+- **Week 4**: TensorFlow.js & Games 📋
+- **Week 5**: Deploy & Optimize 📋
+
+**Total Estimated Time**: 4-5 weeks part-time (~10 hours/week)
+**Ongoing Maintenance**: ~1 hour/month
+
+---
+
+## Maintenance Post-Migration
+
+### Adding New Content (5 minutes)
+```bash
+touch content/posts/2025-01-15-new-post.md
+# Add frontmatter + content
+git add content/posts/2025-01-15-new-post.md
+git commit -m "Add new post"
+git push  # Auto-deploys in <3 minutes
+```
+
+### Dependency Updates (1 hour/quarter)
+```bash
+npm outdated
+# Review changelogs
+npm update
+npm run validate
+```
+
+---
+
+## Architecture Highlights
+
+### Font Toggle System
+**Before (Jekyll + vanilla JS)**: 428 lines of JavaScript
+**After (Next.js + React Context)**: 30 lines of TypeScript
+
+**Features**:
+- Type-safe state management
+- Hydration-safe (no SSR issues)
+- localStorage persistence
+- Welcome modal on first visit
+- Sidebar toggle button
+
+### Why This Minimizes Maintenance
+
+1. **Stable foundation** - Pages Router is 5+ years battle-tested
+2. **Minimal dependencies** - 8 packages vs typical 30+ in Next.js projects
+3. **Static output** - No server to maintain
+4. **Type-safe** - TypeScript catches errors before production
+5. **Git-based workflow** - Same simplicity as Jekyll
+6. **Auto-deploy** - Push to GitHub → live in 3 minutes
+7. **No database** - No schema migrations
+8. **No CMS** - No admin panel or auth
+9. **Exact pinning** - No surprise breaking changes
+10. **Simple mental model** - Markdown → Static pages
