+          # It works because `enabled` is the only alert field no registration
+          # playbook sets. Gatus merges a provider's default-alert into each
+          # endpoint's alert for every field the endpoint left unset, so this
+          # reaches all ~90 of them without editing a single endpoint - and
+          # without unregistering anything. The dashboard keeps checking and
+          # keeps showing red; it just stops sending.
+          #
+          # Deliberately NOT done by deleting the `signal:` provider block:
+          # that would strand ~90 endpoints referencing a provider that no
+          # longer exists, and lose the number and recipients.
