Where should metafields be defined for theme access? 📝

### Explanation Metafields must be created through the Admin API or Store Admin: 1. Metafields are store data, not theme data 2. They persist independently of the theme 3. Can be created via: - Store Admin > Settings > Custom data - Admin API - Apps with proper permissions The theme's settings_schema.json only defines how existing metafields are displayed in the theme editor, but doesn't create the actual metafields.
