/* =====================================================================
   OmegaPack "SAP GUI / ALV" theme  —  reusable stylesheet
   ---------------------------------------------------------------------
   A retro SAP GUI / Fiori-classic look: gradient title bar, tabbed nav,
   grouped "cards", and dense ALV-style data grids. Drop this file in and
   use the documented markup patterns below.

   Design language
     • Palette: SAP steel-blue on light grey; everything is a subtle
       top-to-bottom linear gradient (180deg light->darker) to mimic the
       old GUI's beveled chrome.
     • Typography: Arial / "72" (SAP's font), 12px base, tight line-height.
     • Density: small paddings, 1px hairline borders (#a9bcd4 family),
       3px button radius, 0px card radius (flat panels).
     • Structure: fixed full-height flex column — titlebar / progtitle /
       nav / scrolling main / statusbar.
