/* ================================================================
   BASE CAMP — the calm daily driver. Where Runway (cockpit-dark,
   deadline-driven) and Architect (blueprint-paper, skill-drills) get
   opened from every day. This one is deliberately the quietest of
   the three: soft warm-grey paper, one moss accent, generous space —
   built to be looked at every single evening without fatigue.
   Full light/dark support, since "easy on the eye" here means
   adapting to whenever you actually open it, not committing to one look.
