/* ── Mobile navigation ────────────────────────────────────
   Phones swap the dashboard sidebar for a sticky trigger bar naming the open
   section, and a bottom sheet listing all of them — the sidebar stacked above
   the panel used to spend ten rows of chrome before any content appeared.
   Desktop is untouched: everything here is display:none above 860px, the same
   breakpoint where .dash collapses to one column. Shared by the dashboard and
   the admin console. */
