🔑 KEY FEATURES
═════════════════════════════════════════════════════════════════

✅ Server-Side Authentication
  - Admin routes require admin role
  - Vendor routes require vendor role
  - Shop account routes require customer role
  - Public routes accessible to all

✅ Dynamic Content Rendering
  - User data passed to templates
  - Server-side rendering for SEO
  - Context variables for personalization

✅ Template Inheritance
  - Base templates for consistent layout
  - Block overrides for page-specific content
  - Shared components

✅ Proper URL Structure
  - RESTful URL patterns
  - Vendor code in URL path
  - Clear separation of concerns


⚠️  IMPORTANT NOTES
═════════════════════════════════════════════════════════════════

Route Order Matters!
  ❌ WRONG:
    @router.get("/vendors/{code}")
    @router.get("/vendors/create")  ← Never matches!

  ✅ CORRECT:
    @router.get("/vendors/create")  ← Specific first
    @router.get("/vendors/{code}")  ← Parameterized last

Authentication Dependencies:
  - get_current_admin_user → Admin pages
  - get_current_vendor_user → Vendor pages
  - get_current_customer_user → Shop account pages

Template Paths:
  - Must match directory structure
  - Use forward slashes: "admin/dashboard.html"
  - Base path: "app/templates/"


🧪 TESTING CHECKLIST
═════════════════════════════════════════════════════════════════

Admin Routes:
  □ /admin/ redirects to /admin/login
  □ /admin/login shows login form
  □ /admin/dashboard requires auth
  □ /admin/vendors shows vendor list
  □ /admin/vendors/{code}/edit loads correctly

Vendor Routes:
  □ /vendor/ACME/ redirects to login
  □ /vendor/ACME/login shows login form
  □ /vendor/ACME/dashboard requires auth
  □ All /admin/* subroutes work

Shop Routes:
  □ /shop/ shows products
  □ /shop/products/{id} shows product
  □ /shop/cart works without auth
  □ /shop/account/dashboard requires auth
  □ /shop/account/orders shows orders


🔧 COMMON ISSUES
═════════════════════════════════════════════════════════════════

Problem: "Template not found"
→ Check templates directory path
→ Verify template file exists
→ Check forward slashes in path

Problem: "401 Unauthorized"
→ Check auth dependency is defined
→ Verify token is being sent
→ Check user role matches requirement

Problem: "Route conflict"
→ Reorder routes (specific before parameterized)
→ Check for duplicate routes
→ Review route registration order

Problem: "Module not found"
→ Check __init__.py exists in directories
→ Verify import paths
→ Restart server after adding files

💡 PRO TIPS
═════════════════════════════════════════════════════════════════

1. Test incrementally
   - Migrate one section at a time
   - Keep old routes until new ones work

2. Use template inheritance
   - Create base.html for each section
   - Override blocks in child templates

3. Pass user data in context
   - Available in templates via {{ user.name }}
   - No extra API calls needed

4. Handle both auth and non-auth
   - Some routes public (login, register)
   - Some routes require auth (dashboard)

5. Follow RESTful patterns
   - /vendors/create not /create-vendor
   - /vendors/{code}/edit not /edit-vendor/{code}
