+ * GET /api/settings/profile — read the caller's ZITADEL profile.
+ * Returns first/last/display name and email. Used by the settings
+ * page server component to populate the form.
+ *
+ * PUT /api/settings/profile — update first + last name. Email is
+ * NOT mutable here — changing email needs verification flow that
+ * ZITADEL's own self-service UI already provides; we don't
+ * duplicate that.
+ *
+ * Authorization: any authenticated user can edit their own profile.
+ * The PAT (ZITADEL_SA_PAT) is used to call the ZITADEL v2 user
+ * service, but only against the caller's own userId. There is no
+ * userId field on the request — it's always derived from the
+ * session, so the route can't be abused to edit other users.
