# Lineage brand kit

Everything you need to represent Lineage correctly. Machine-readable tokens are
in `brand.json` (served at `/brand/brand.json`). The full downloadable archive
is `/brand/lineage-brand-kit.zip`.

## The mark — "The Clearing Cross"

Two tapered blades — cyan over emerald — meeting at an open centre. Cyan reads as
interaction (incoming); emerald reads as action (settling). Each blade brightens
toward the centre.

Variants (in this kit and under `/brand/`):

- `lineage-mark.svg` — primary full-colour mark. Use at 24px and above.
- `lineage-mark-mono.svg` — single-colour knockout for print, etch, or watermark.
- `lineage-icon.svg` — plated app icon on a dark rounded square (app store / touch icon).
- `lineage-icon-min.svg` — 16px-minimum glyph with a converged (solid) centre.
- `favicon.svg` — favicon tile.

## Usage

Do:

- Pair the glyph with the "Lineage" wordmark set in Space Grotesk 600, tracking -0.02em.
- Keep the emerald/cyan duotone and the blade taper.
- Give the mark clear space of at least the height of one blade on every side.
- Use the converged-centre glyph (`lineage-icon-min.svg`) below ~20px; the open centre elsewhere.

Don't:

- Recolour the mark outside the emerald/cyan system, add a "plopped dot" centre, or stretch it.
- Reserve the glow for more than one focal placement.
- Set the wordmark in the body typeface.

## Colour

Dark-only system. Emerald is action (rationed), cyan is interaction. Full token
list with OKLCH (source of truth) and derived sRGB hex is in `brand.json`.

## Typography

- Display / headings / wordmark: Space Grotesk (600, -0.02em)
- Body: Inter
- Code / data: JetBrains Mono

Fonts are open source (Google Fonts) — see the URLs in `brand.json`. Display and
body are never the same family.
