Account
ProfileNameForm, ChangeEmailForm, ChangePasswordForm, TwoFactorSection and ManageOnSignInSite from packages/ui, each wired to a fixture that succeeds, rejects a specific input, or fails outright.
Profile name
Whether the frontend-API session needs the current password to reissue a sensitive change.
Password
Two-factor authentication
Both resting states fetch nothing. The QR code is a fresh TOTP secret and the backup codes are a recovery secret, so each appears only after the press that asks for it.
Sessions
The control someone acting on a suspected compromise reaches for. The auth provider revokes every session and offers no way to spare the caller's, so the copy names this browser too.
Manage-elsewhere fallback
When the auth-domain session can't be reached from this browser (a preview host, or a third-party-cookie block outside Chrome).
