/* Scrollable nav region.

   .sidebar is a 100vh flex column: brand, building selector, nav, foot. NavMenu
   renders its sections as several sibling divs, and with no scroll container
   between them and .sidebar their combined height simply exceeded the column on
   a full manager menu. .sidebar-foot's `margin-top: auto` only positions when
   there is free space, so under overflow the nav boxes shrank, their content
   spilled, and the foot — a later sibling in the same stacking context — painted
   over the last nav item (settings-cmi for a SyndicManager), swallowing its
   clicks.

   min-height: 0 is the load-bearing half. A flex child's default
   `min-height: auto` resolves to its content height, so without this the
   container cannot shrink and overflow-y never engages. */
