/* DSNET Portal Sidebar (Phase 8 - mobile fix)
   Fixes: mobile menu not showing due to portal.css hiding .portal-sidebar.
   - Forces display on mobile (overrides portal.css display:none).
   - Uses header height CSS var so drawer sits below header.
   - Keeps overlay below header so toggle stays clickable.
