/* ---- narrow: nothing is dropped, everything gets a smaller shape ---------
   The viewbar carries 10 controls whose labelled min-content is ~700px. Below
   720 the labels go (the button keeps title + aria-label, so it is still named
   to pointer and screen reader); below 600 even the icon-only row does not fit
   on one line, so the six view controls wrap onto a second line of their own
   and --viewbar-h grows to match. No control is hidden without a route to it:
   the two topbar buttons that do disappear (keyboard help, theme toggle) are
   both items in the account menu, which stays. */
