# Strelva Brand Kit

This directory is the authored source for Strelva identity assets. The rendered guide lives at `/brand-system`.

## Direction

**Proof Cairn:** a calm nocturnal instrument for work that reaches a verified end state.

The three mineral strata represent controlled stages. The sage witness point marks completion. The symbol remains recognizable in one color.

## Canonical system

- Dark is the brand.
- Fraunces is the display and wordmark family.
- DM Sans is the body and interface family.
- Sage is reserved for Strelva and interaction.
- Success green describes operational completion and is not interchangeable with sage.
- Light artwork exists for documents and print, not as a second product theme.

## Logo rules

- Use supplied artwork.
- Keep the witness point as the only colored part.
- Keep at least one witness-point diameter of clear space.
- Never stretch, rotate, shadow, outline, or gradient the mark.
- Never create a separate Strelva Labs mark.
- Never use mountains, trails, bison, snowflakes, AI sparkles, or neural-network imagery.

The SVG wordmark and lockups use Fraunces text so the codebase remains editable. Use the committed PNG lockups when the receiving application cannot load Fraunces.

## Sources of truth

- Runtime geometry: `src/lib/brand-system.ts`
- Runtime components: `src/components/Logo.tsx`
- Product tokens: `src/app/globals.css`
- Brand guidance: `DESIGN-KIT.md`
- Portable colors: `brand-kit/tokens/strelva-colors.css` and `.json`

Run `npm run brand:build` after changing source artwork. It synchronizes public
downloads, generates the transparent mark PNG scale, and rebuilds runtime icon
tiles from the canonical SVG.
