 *
 * The tightening used to start at 380px, on the stated assumption that there
 * were two controls: login and background data. A signed-in administrator has
 * three, because ADM sits beside PROFILE, and three do not fit until well
 * above 380. On a 390px phone the ADM button hung nine pixels off the right
 * edge and took the whole page into horizontal scroll with it — visible only
 * to admins, which is exactly the sort of thing nobody reports. The rescue now
 * starts where three controls actually stop fitting.
