/*
  Eliana "Living Intelligence" token system.
  Dimensional, luminous, quietly powerful, editorial. Not a SaaS admin palette.

  Two families are reserved as decorative/brand accents (plum + teal) and are
  never reused for operational danger. Danger (critical/warning) lives in a
  completely separate red/orange family. Amber ("expected limit") is a third,
  distinct hue-family again -- reaching a safety limit is normal operation,
  not a warning, and must not read as one.
