/* ─────────────────────────────────────────────────────────────────
   ADMIN — SITEMAP

   The sitemap lives in its OWN top-level shell (#sitemap-shell in
   legacy.html, activated by the inSitemap branch in router.js). When
   active it fills the entire viewport — no admin sidebar, no admin
   topbar, no marketing chrome. Close button in the toolbar (red X)
   returns to #admin/courses.

   Layout inside the shell: header (full width) + 3-column body
   (legend / canvas / side panel). Narrow viewports collapse the side
   panel below the canvas and hide the legend.
