   Boabat Alnoor - 2026 theme
   --------------------------------------------------------------------------
   Layout, typography and component system follow the reference site
   emc-egypt.net (Montserrat headings over Roboto body, a full-bleed hero,
   an animated stat band, filtered project cards, a partner marquee).
   The palette stays Boabat Alnoor's own green/navy - swap the --brand-*
   tokens below to re-skin the whole site.
   Written standalone: it does not depend on the legacy boabat-style.css.
