Typography

auri ships a type scale, not a typeface. Components inherit whatever font your application uses, so they look native in your product on day one — the scale is what makes twelve components read as one object.

The three roles

Role	Tokens	Sample
value — the big number	1.75rem / 600, tracking −0.025em	4.8%
label — what it is	0.8125rem / 500	Error rate
caption — the context	0.75rem / 400	last 15 min

Numbers never jiggle

Every value that can update in place uses font-variant-numeric: tabular-nums, so a stat climbing from 0.4 to 4.8 doesn't shove its neighbors. Streaming UI lives or dies on this detail:

Why components inherit your font

A catalog drops into someone else's product. Shipping a typeface would make agent-rendered surfaces look like a foreign object inside the host app — so the components set sizes, weights, and numerics, and leave the family to you.

This site's voice: Geist

The docs are set in Geist (Vercel, SIL OFL 1.1), self-hosted as variable fonts — light, medium, bold — with Geist Mono for the wire and the logs. That's the site making a choice a host app is equally free to make.
