System settings and runtime configuration
System Settings lets admins review runtime health and update settings that override or complement environment configuration.
What belongs here
Use System Settings for app-level values such as email provider settings, marketplace markup, registration behavior, and operational flags exposed by the page.
Environment-only secrets and server paths should remain in the configured environment file outside the web root.
After saving
Re-test the affected workflow immediately. For email changes, send a test message. For marketplace changes, open a listing and checkout path.
Some worker processes may need restart if they read configuration at startup.
Security notes
Treat API keys, SMTP passwords, Stripe keys, PayPal keys, and webhook secrets as sensitive even when they are stored through admin forms.
Never paste production secrets into screenshots, support tickets, or help article examples.
