// The Options dialog. Lane GUI.
//
// docs/03-gui-spec.md §4: every control here maps 1:1 onto a settings.* key from
// contracts/schema/types/Settings.schema.json. The spec's "File Types" tab turned out to
// have real backing after all (capture.monitoredExtensions/monitoredMimeTypes/
// autoStartTypes are settings.* keys, not Category — a mistake in an earlier pass here,
// caught while checking this dialog covers all 43 keys against the now-live real veloxd);
// it is named "Capture" below to match what it actually configures. "Site Logins" still
// has no settings.* key (credentials go to the Secret Service) and stays out.
