 * FIELD · Typography tokens
 * Display = Archivo (grotesque, tight, structural). Body =
 * Hanken Grotesk (humanist, calm, legible at small sizes).
 * Mono = IBM Plex Mono (the "data register" — anything machine-
 * generated, hashed, timestamped, or identity-bearing).
 *
 * The product uses four type REGISTERS, a real and load-bearing
 * idea worth keeping:
 *   R0 Command    — tab labels, section heads, status chips (mono-ish, uppercase, tracked)
 *   R1 Narrative  — rationale, amendment text, body prose
 *   R2 Data       — IDs, UUIDs, timestamps, criteria, lab values (mono)
 *   R3 Annotation — system hints, lint, audit metadata (mono italic)
