+//   - email and password sign-in, without e-mail verification (an app that sends mail turns it on)
+//   - the person's own account deletion (`/delete-user`): the revocation relay hands it to the app's
+//     account flow, which erases the person's data in every module (apps/web/src/server/better-auth.ts)
+//   - the admin plugin: an administrator disables (`banned`) a user, which ends every session of the
+//     user and refuses the next sign-in; the session validation refuses a disabled user as well
+//   - rate limits kept in the deployment's own table, since a Convex function keeps no memory
