/* The mobile off-canvas sidebar reuses .hb-sidebar for its visual styling, but it
   must never participate in the .hb-wrapper flex layout the way the static sidebar
   does. Because app.css loads after bootstrap.min.css, the plain .hb-sidebar rule
   above (position: sticky) would otherwise win over Bootstrap's .offcanvas rule
   (position: fixed) at equal specificity, leaving a phantom 240px column in the
   flex row even while the panel is hidden. This higher-specificity rule forces
   correct off-canvas behavior regardless of stylesheet order. */
