/* Contri. One stylesheet for the site and the app.

   Direction
   - Product: ajo savings circles for Nigerians; a NEAR contract holds the pot
     and pays each turn.
   - Character: steady, communal, exact.
   - World: adire indigo on cotton, the collector's ledger card.
   - Moments: the turn ring, and the seat NFT the contract draws.
   - Signature: numbered seats around a ring (logo, favicon, ring, NFT).

   System: 4px spacing grid, weights 400 and 500 (600 only for the wordmark),
   one accent (adire indigo), three text roles, hairlines, one easing curve.
   One typeface, Instrument Sans, self-hosted so no font request leaves the site. */
