  Palette is anchored to the Tailwind "sky" scale so the page chrome and the
  Three.js geometry (sky-500 / sky-600 / sky-800) share the same family.
   - bg uses sky-50/100 for surfaces, white for elevated cards
   - text uses sky-900 / slate-500 / slate-400 for the three text levels
   - accent is sky-500 with sky-600 hover
