/*
  Palette grounded in the "Financial Dashboard" + "Minimal Swiss" design
  patterns (data-dense, high-contrast, restrained color used only for
  status). Dark is the default (matches OLED/low-eye-strain guidance for a
  tool operators keep open all day); a light variant follows the OS
  preference automatically. System font stack only - no third-party font
  requests, consistent with the strict same-origin CSP.
