   SKY Homes Development — landing page styles

   Design follows the printed portfolio: white pages, generous air, hard-edged
   photography, thin geometric headings, terracotta sub-headings on navy body
   text. Layout uses CSS logical properties so the Arabic (RTL) view mirrors
   automatically from the same rules.
