// The Geist UI scheme.
//
// Geist UI is Vercel's system: a single accent ramp (`accents_1`…`accents_8`)
// instead of a colour scale, a black or white page, and a blue that plays
// the role of both the brand colour and the success colour. The values here
// are the published `presets/default.ts` and `presets/dark.ts` palettes and
// expressiveness tokens. Geist publishes one radius, 6px, so the shape slots
// share it; the unit is 16px, which sets the type ramp and the control
// heights; and the font family is the published Inter stack.
