### Admin Features

**Tech Stack:**
- Next.js 14+ with App Router
- Tailwind CSS for styling
- Supabase for auth and database
- Stripe for payments
- MDX for blog/guide content
- Vercel for hosting

**Design System:**
- Custom font pairing (serif + sans-serif)
- Cream/forest green/amber color palette
- Consistent spacing and components
- Mobile-responsive throughout
- Subtle animations and transitions

**Database Schema:**
- Users (with Supabase Auth)
- Courses
- Enrollments
- Content/Lessons
- Blog posts
- Newsletter subscribers

**Start Simple:**
Begin with marketing pages + blog only. Add course content and student portal after the foundation works. Payment integration comes last.

**File Structure:**
```
/app
  /page.tsx (homepage)
  /blog
  /guides
  /courses/[slug]
  /dashboard (student portal)
  /admin
/components
  /marketing
  /blog
  /course
  /portal
/content
  /blog (MDX files)
  /guides (MDX files)
/lib
  /supabase
  /stripe
```

This is a larger project. Focus on getting the marketing site and blog working first, then layer on the course/payment features.
