/* Mobile: #chrome-header is flex with the brand (nowrap text, can't shrink)
   fighting nav and the session widget for room on one line. nav's
   overflow-x:auto gives it an automatic min-width of 0 (new formatting
   context), so flexbox happily crushes it to a near-invisible sliver instead
   of wrapping — with scrollbar-width:none hiding the fact it's scrollable at
   all. Force nav onto its own full-width row below brand+session instead, and
   bump touch targets that are comfortable with a mouse but small for a
   thumb. */
