/* ═══ LESNAR AI · FIELD RECORD ═════════════════════════════════════════════
   One design language, three sources:
     RECORD   · measured channels and readings: the work's own data is the image
     TERRAIN  · places and roads: where a system actually runs, on real geometry
     CONTACT  · captured frames: every screen shown with what, whose data, how
   Rules: nothing drawn for effect; colour means something; provenance travels
   with every artifact; mono only for data and metadata, never for voice.

   Type: Archivo (one variable family, width 62–125) + IBM Plex Mono.
     condensed 62% · statements      normal 100% · reading      wide 125% · places
   ═══════════════════════════════════════════════════════════════════════ */

/* Self-hosted fonts (SIL OFL, licences in /assets/fonts/). Archivo is "optional", not "swap":
   its condensed widths reflow a fallback badly (measured CLS 0.27 with swap). It is preloaded, so it
   normally arrives inside the 100 ms window; on a slow connection the text shows at once in the
   fallback and never shifts. ("block" hid text for up to three seconds instead.) */
