/* ── Design principles for this platform ──────────────────────────────────
   Users are trusting us with real money. The design should feel calm,
   precise, and quietly confident — closer to a well-made instrument panel
   than a consumer app trying to hype anyone up. Never dark-pattern; every
   satisfying detail (the pulse on a live instance, the tick counter) is a
   HONEST reflection of what's really happening, not decoration standing in
   for missing information.
