   When collapsed, hovering an icon shows a small floating pill label to the
   right of the 48px rail.

   Overflow fix: the sidebar has overflow:hidden in collapsed state to prevent
   text bleed.  We override it here to overflow:visible so the ::after pill can
   escape the rail; width is already constrained to 48px by the grid column so
   the sidebar box doesn't widen.  The ::before clip-shield (not needed here)
   and existing span{display:none} rule handle text bleed.

   No JS required — pure CSS.  Only active under .app.sidebar-collapsed so the
   tooltip never shows when the sidebar is expanded (labels are already visible).
