/* NomadFS site: "night-caravan cartography", the app's own theme.
   A navigator's chart for a caravan of devices crossing the desert at
   night: dune contours and stars behind, instrument plates with amber
   registration ticks in front, numbered plate labels. Amber/terracotta is
   the caravan's lamp (action), Oasis teal is signal (anything live).
   Fonts: OFL, bundled latin subsets (fonts/README.md). */
