- Extensible system: admins can add custom gateways with any config fields
- System gateways are protected (can't delete, only toggle)
- Dynamic config fields (key-value pairs) for API keys, secrets, merchant IDs
- Checkout page fetches active gateways from API and renders them dynamically
- Payment transactions are created when orders are placed with online gateways
- Orange theme throughout with professional card-based admin UI
