/* ==========================================================================
   أرباحي - Professional Responsive Enhancement Layer
   --------------------------------------------------------------------------
   Loaded AFTER style-desktop.css / style-mobile.css / landing-*.css so it
   can override and refine the existing responsive behaviour with a more
   modern, mobile-first, touch-friendly experience.

   Goals:
     • Fluid typography (clamp) so headings scale smoothly across screens
     • Better touch targets (min 44x44) for buttons and nav items
     • Robust grids that reflow on any screen size without overflow
     • Improved sidebar / drawer behaviour on mobile
     • Tables that turn into cards on narrow screens
     • Forms that are usable on phones (16px+ font, generous spacing)
     • Print-friendly tweaks for invoices / receipts
     • Better safe-area handling for notched phones (iOS)
