   REKOVE Business Solutions Limited - Responsive Stylesheet
   ISO229 Assessment 3 (A3): Responsive HTML5 + CSS3 Website

   Approach: MOBILE-FIRST. The base rules below style the smallest screens.
   min-width media queries then progressively enhance the layout:

     Base    : 0 - 599px      phones (single column)
     Tablet  : 600px and up   two-column grids, horizontal header
     Laptop  : 900px and up   multi-column page layouts
     Desktop : 1200px and up  wider spacing, max content width

   Contents
     1.  Design tokens (CSS custom properties)
     2.  Reset & base elements
     3.  Typography
     4.  Accessibility helpers (skip link, focus)
     5.  Layout utilities (container, section spacing)
     6.  Header & navigation (Flexbox)
     7.  Hero (Grid)
     8.  Buttons
     9.  Cards & feature grids (CSS Grid)
     10. Numbered steps (Grid + CSS counters)
     11. Tables (responsive stacked tables)
     12. Figures & images
     13. Page intro banner & in-page links
     14. Contact page layout & form (Grid)
     15. Footer (Grid)
     16. Media queries (tablet / laptop / desktop)
     17. User preference queries (reduced motion) & print
