/* ============================================================
   PALETTE — THE UNIT (Present tense, now)
   Screen-lit blue on cold concrete-black: the glow of somebody
   else's phone in a storage unit at night. Deliberately COOLER
   and higher-chroma than the Red-Eye's warm Pan-Am blue so the
   two blues never read as the same trilogy.

   Present tense fonts: Space Grotesk (display + body) + IBM Plex
   Mono (codes, coordinates, metadata).
