// of PUT /api/me/profile so the Android Settings → Profile screen can
// read its starting state from a GET before the user has done a first
// save.
//
// The full profile matters: a form seeded with display_name=null and
// email=null would, on save, submit empty strings, which
// handleUpdateMyProfile treats as "clear to NULL" — destroying the stored
// values. The web app's narrower User type ignores the extra fields.
