+### Fixed
+- **Removed every native `alert()`/`confirm()` call**, replacing them with `app.messages.action`/`confirm`/`toast`. Native `confirm()` blocks all further browser events on the page (discovered live, mid browser-verification of the 1.6.0 `app.messages`/`app.modal` adoption, on `directory.ejs`'s "Rotate Client Secret" — it froze the whole tab). Also deleted `app.user.remove`/`app.oauthClient.remove` in `public/js/app.js`, which had native `confirm()` guards and zero callers anywhere in the app.
