# Brand kit: Typography | Slingshot

> Slingshot is building agentic brand systems: a brand delivered as files, MCP servers and CLIs that people and agents both work from.

Three faces with separate jobs. Families and sizes are in `tokens.json`.

| Token | Face | Job |
| --- | --- | --- |
| `font.statement` | Exposure, a serif (licensed separately, not in this kit) | The one statement on a surface |
| `font.text` | Geist (SIL Open Font License) | Everything a person reads |
| `font.label` | Geist Mono (SIL Open Font License) | Section labels and step numbers |

## Rules

- **Set one statement per surface in the serif, and nothing else.** Because the serif marks the single idea the surface exists to say; a second serif line competes with it.
- **Balance the statement's lines and never break a hyphenated word across them.** Because a statement read in one glance should not end on an orphaned word or a dangling "Claude-".
- **Set body copy in Geist at 15px or larger.** Because smaller text strains at the distance people hold phones.
- **Set labels in Geist Mono, uppercase, 11px, in stone.** Because labels name a section without competing with its content.
- **Fall back to the listed system fonts, never to a different brand face.** Because a missing font should degrade quietly, not change the brand.

## When to use

- **Make a brand usable by AI agents:** Slingshot turns a brand into files, tokens, an MCP server and a CLI, so the agents a team already uses can make on-brand pages, decks and copy without guessing.
