   Left sidebar shell  (2026-10)
   The section nav moved from a top navbar row into a fixed left rail. One
   markup block in base.html serves both: Bootstrap's `offcanvas-lg` renders it
   as a static rail from 992px up, and as a slide-over drawer below that.
   Bootstrap forces `background-color: transparent !important` on .offcanvas-*
   above the breakpoint, so the desktop rail background needs !important back.
