   Palette is deliberately institutional — deep blue, slate, warm
   paper — because grantmakers and gaming-studio CSR reviewers are a
   primary audience alongside program participants. This should read
   like an education foundation, not a games brand.

   The accent is green, sampled from the actual logo (a joystick
   growing into a tree) rather than picked freehand: --green-deep is
   pulled from the trunk's dark olive, --green from the leaf sage,
   lightened/saturated just enough to hold up as UI (borders, links,
   focus rings) at a11y-safe contrast. See website/assets/README.md.
