/* ============================================================
   shell.css — the one consistent left rail (paired with shell.js).
   Theme-token styled (flips light/dark). Replaces the per-page navs so
   every dashboard page shares ONE rail. Fixes: pilot-card overlap (the
   footer is short + in normal flow, never a clipped sticky box), and the
   "nav changes per page" confusion (same rail everywhere).
   ============================================================ */

   (.app and .app-shell are both `grid-template-columns: 248px 1fr`),
