Install

The file lands as app/vibra-noir.css. Import it after your globals and set data-preset="noir" on <html>, or on any wrapper.

npx shadcn@latest add @vibra/theme-noir

Needs the @vibra registry in your components.json — set it up once.

The stylesheet

app/vibra-noir.css
/* Noir — pure black on white and white on black, with no middle ground — developer-first and aggressively minimal.
 *
 * After tweakcn's palette (https://www.shadcnblocks.com/theme/vercel), mapped onto every token
 * vibra.css defines and held to Vibra's contrast floors: where a value moved,
 * it moved the least it could — a fill that was too light to read as a word
 * is the same hue, deeper. The typefaces the original names are not carried;
 * a preset is colour, radius and elevation, and the face is the page's own.
 *
 * Generated by scripts/build-presets.ts. Edit scripts/presets/sources, not this file. */
