package dto_admin

// Notifications the admin panel triggers.
//
// Two shapes, because there are two kinds of trigger:
//
//   - **A message the admin writes.** The panel supplies the words.
//   - **An event the panel handled.** Profile verification and withdrawal
//     approval are decided in the panel, not in this API, so the panel tells
//     the API what it did and the API sends the notification with the same
//     wording every other notification uses. That keeps one set of templates
//     rather than the panel inventing its own copy.
