   OVE Africa
   Brand: Poppins, navy #003366 + black, secondary off-white, teal, bronze, gold.
   Palette strategy: calm, light neutrals carry the page; navy is the accent,
   as it is in the logo. A neutral charcoal (the brand black, softened) is used
   sparingly for the calculator, the mission photo and the footer — gold only
   appears on those dark surfaces, where it reads well.
   Sections are layered "sheets" that slide over one another.
