# The 19th Brand OS

> The living home for The 19th brand. Built for the team, and for AI.

North Star: Love the game. The 19th awaits.

## The framework

The brand kit lives as a small set of markdown files. Each is linked below. Read in order for orientation, or pick the one you need for the job at hand.

- [Index](/raw/00-index.md): What The 19th Brand OS is, and how to use it.
- [Brand DNA](/raw/01-brand-dna.md): What it is, who it is for, how we position it, the one-liner.
- [Voice & Tone](/raw/02-voice-and-tone.md): How we sound, three-beat lines, "the sim" language, do / don’t.
- [Visual System](/raw/03-visual-system.md): Logo suite, colour, typography, clear space and misuse, downloads.
- [Memory](/raw/05-memory.md): Decisions, dates and open items — the running notebook.

## Visual tokens

### Colour

| Name | Role | Hex | RGB | Pantone | Text on | Use |
|---|---|---|---|---|---|---|
| Deep Navy | Primary | #1A2D4E | 26 · 45 · 78 | 533 C | #B4D9D2 | Leads the identity. Backgrounds, type, the dominant 60%. |
| Sea-Glass | Secondary | #B4D9D2 | 180 · 217 · 210 | 565 C | #1A2D4E | Supports navy. Accents, fills, the reversed logo. Never as text on white. |
| White | Neutral | #FFFFFF | 255 · 255 · 255 | — | #1A2D4E | Clean space, and emphasis text on navy. Keeps the two-colour identity breathing. |

Balance: Navy 60% / Sea-Glass 30% / White 10%.
Sea-glass fails as text on white — accent and background only.

### Typography

- **Headings** — Satoshi Bold / Black, ALL CAPS. Caps with light letter-spacing (≈40–80 units). Build hierarchy with weight, not extra colours.
- **Body & UI** — Satoshi Medium, Sentence case. Body 10–11pt, line-height ≈1.5, reading measure 45–75 characters. Tabular numerals for prices and times.

The script "The / th" and the "19" in the logo are custom lockup artwork, not a font. Never re-type the name to imitate it — always use the supplied logo files. Satoshi is free from Fontshare (fontshare.com).

## Downloads

- [Logo suite](/downloads/the-19th-logos.zip) (SVG + PNG · 4 colourways): Flag badge, small-use mark and wordmark. Vector SVG in Deep Navy, Sea-Glass, White and Black.
- [Satoshi typeface](/downloads/satoshi.zip) (woff2 + OTF/TTF): The brand font — web-ready woff2 and desktop files. Free from Fontshare.

## How to use this index

Each spine link returns the source markdown of one part of the brand. Load any single file for a focused task, or several for cross-cutting work. The pretty pages at the same URLs (without `/raw/`) are for humans.
