/* Sovereign — Typography (Geist foundation)
   Two fonts, one voice. Geist Sans carries everything human; Geist Mono is the
   machine voice — cryptographic digests, keys, canonical JSON, and uppercase
   technical labels. Signature move: aggressive negative tracking at display sizes,
   relaxing to 0 as text shrinks, going slightly positive (+0.04em) on mono caps. */
