Complete WooCommerce-style page architecture implementation:
Backend (already committed):
- API endpoint to fetch WordPress pages
- spa_pages field in appearance settings
- is_spa_page() checks in TemplateOverride and Assets
Frontend (this commit):
- Added page selector UI in Appearance > General
- Dropdowns for Shop, Cart, Checkout, Account pages
- Loads available WordPress pages from API
- Saves selected page IDs to settings
- Info alert explaining full-body rendering
UI Features:
- Clean page selection interface
- Shows all published WordPress pages
- '— None —' option to disable
- Integrated into existing General settings tab
- Follows existing design patterns
How it works:
1. Admin selects pages in Appearance > General
2. Page IDs saved to woonoow_appearance_settings
3. Frontend checks if current page matches selected pages
4. If match, renders full SPA to body (no theme interference)
5. Works with ANY theme consistently
Next: Test page selection and verify clean SPA rendering
