/* ============================================
   Tekvwa Analysis - Excel/SPSS Style Navigation
   Modern Ribbon Interface

   Strictly black & white per the app's design constraint — no accent color anywhere in this
   file (the previous version used a Windows-blue #0078d4 accent for hover/active/links; every
   occurrence below is now a shade of black/gray instead). Chrome that sits directly against the
   themeable content area (ribbon tabs/panel, status bar, dataset bar, dropdown menus) uses the
   CSS custom properties defined in base.html so it inverts correctly with the dark-mode toggle.
   The menu bar itself keeps its own fixed dark background by design (a permanent title bar, like
   a desktop app's, rather than something that should flip white in light mode) — only its color
   values were de-blued, not converted to the theme variables.
   ============================================ */

/* Sticky wrapper around the menu bar + ribbon tabs + ribbon panel, so the whole nav
   (including the File menu's Dashboards link and every ribbon-tab button) stays reachable
   while the page content scrolls, instead of scrolling away with it. */
