/* Geist + Geist Mono — a clean, modern, tech-forward neo-grotesque
   family. Geist drives headings and body copy — legible, unfussy,
   built to carry a "clarity" message without decoration getting in
   the way. Geist Mono is mixed in for data-native details: eyebrow
   labels, coordinates, metrics, engine readouts — the small technical
   texture that signals "this company actually handles data." */
