     Brand palette — three official colors, used at a ~79 : 14 : 7 ratio
     (green : red : gold) across the site.

       • GREEN  rgb(0, 103, 71)   #006747  — dominant ~79%: header nav,
         footer, hero/page-hero overlays, primary buttons, links, section
         tints, and 10 of the 12 program accents. The default brand color.
       • RED    rgb(176, 32, 22)  #B02016  — secondary ~14%: the Education
         focus accent, secondary hero CTA, data-quality alerts, a few badges.
       • GOLD   rgb(244, 195, 0)  #F4C300  — sparing ~7%: donate CTAs,
         footer headings, hero label, and the Zakat focus accent.
     Keep this distribution in mind when adding new colored elements.
