   Responsive — phone shell: sidebar out, bottom tab bar in

   specificity, so an unmediated rule declared *after* this block would win
   at every width, including a phone's, for any property both rules set —
   silently, since the override wouldn't even need to look responsive. This
   block used to sit mid-file, above .page-header-actions, .seq-step-actions
   and .brief-actions, which set overlapping flex properties at equal
   specificity; it stayed harmless only because none of them happened to
   touch flex-wrap. .tabbar/.tab-item (declared near the top of the file)
   are exposed to the same hazard, which is the other reason this block —
   the only place that overrides them — belongs after everything it touches.
