   ImmersiveMinds — Design Tokens
   Palette drawn from construction materials: moss (grass block), pine
   (deep forest), clay (baked earth), stone (grey block), sky (open air).
   Blocky, hard-edged geometry throughout — no border-radius, hard shadows
   instead of blur — nodding to voxel construction without literal pixel
   gimmicks. Serif body copy keeps the humanities/storytelling side of the
   work legible and warm against the constructive display type.
