   DataroxIT Web Platform — Shared Design System (base.css)
   ----------------------------------------------------------------------------
   ONE stylesheet powers every product marketing site. Each product ships a tiny
   theme file (see Webmaster/templates/theme.css) that overrides only the BRAND
   TOKENS block below. Do not hardcode colors in product pages — use tokens.

   Sections:
     1. Brand tokens (override per product)
     2. Structural tokens (rarely change)
     3. Reset & base elements
     4. Layout shell & header/nav
     5. Buttons
     6. Hero
     7. Cards, grids & sections
     8. Pricing & comparison table
     9. Forms & feedback
    10. Footer
    11. Utilities (reveal, back-to-top, badges)
    12. Responsive breakpoints
    13. Reduced motion
    14. Dark mode
