   OPEN GROUND — landing styles (terminal-only era)
   The app's "paper / cartographic" identity: cream paper ground, ink-brown
   text, terracotta accent, Fraunces serif display, Instrument Sans body,
   JetBrains Mono for everything terminal. The one deliberate contrast:
   real terminals render as deep-ink panels — dark glass set into the paper.
   Tokens mirror tailwind.config.ts.
