/* ════════════════════════════════════════════════════════════════════════
   NEXUNOVA RMS — SHELL CHROME  (Nav phase · 2026-06-12)
   ────────────────────────────────────────────────────────────────────────
   The thin utility topbar that REPLACES the retired Aurora mega-menu, plus
   the shared "+ New" / company / popover menus. Persistent sidebar + thin
   topbar = the QuickBooks / SAP / Stripe standard.

   Tokens only (--fk-*). No gradients, no glows, no bounce. One shadow
   (--fk-shadow). Transitions 150–200ms ease. Loaded AFTER components.css so
   these win the cascade without !important. Scoped to #s-app so no page
   content is touched.
