/* ═══════════════════════════════════════════════════════════════════════════
   SBR Air — shared/ui/sbr-air.shell.css  (V2 application shell)
   Charcoal sidebar + white header for the Dashboard, per Visual Design System v1.1 §10 and the frozen Jobs
   Operations Board. Uses the V1 tokens (the sidebar and header carry class "sa-scope").
   Selectors are limited to the two shell containers (.sa-scope.sa-nav, .sa-scope.sa-topbar), the nav scrim and
   the Dashboard layout container (body.mode-admin #sbr-admin-app). Module screens inside .content are untouched.
   Responsive (v1.1 §10, §23): ≥ 1280 expanded 232 px (user may collapse to the 64 px rail, remembered);
   1024–1279 rail 64 px; < 1024 hidden — the header menu button opens the nav as a 280 px overlay.
   State classes are set by shared/ui/sbr-air.shell.js: is-rail, is-collapsed, is-overlay.
