   constraint on narrow phones -- flex-shrink (not fixed widths) so buttons
   shrink together and guarantee a fit down to a ~2rem floor, rather than
   hand-computed breakpoints that could overflow on a given device width.
   2.8rem is the ideal/max size (reached on wider screens); the floor still
   comfortably fits a 320px-wide viewport (checked against this page's
