/* ============================================================
   Cromwell Works — modernist single-family system.
   - Geist (sans, all display + body)    — precise neo-grotesque
     in the Söhne / Neue Haas family. One family, multiple
     weights (300/400/500/600) carries the entire hierarchy.
     Tight tracking and large display sizes do the work the
     serif used to do; nothing is decorative.
   - Geist Mono (status tags, indices)   — same designer; used
     in small caps-feel for metadata so it reads as machine-set.
   No serif. No second family. Hierarchy = weight + scale + rules.
