  // Similarly, if x is above/below a warning threshold that triggers
  // above/below, then the scorecard is in a warning state - unless x also puts
  // it in a danger state. (Danger trumps warning.)
  //
  // As an example, consider a scorecard with the following four thresholds:
  // {
  //   value: 90,
  //   category: 'DANGER',

  // },
  // {
  //   value: 20,
  //   category: 'WARNING',
  //   trigger: 'BELOW',
  // }
  //
  // Then: values less than or equal to 10 would put the scorecard in a DANGER
  // state, values greater than 10 but less than or equal to 20 a WARNING state,
  // values strictly between 20 and 70 an OK state, values greater than or equal
  // to 70 but less than 90 a WARNING state, and values greater than or equal to
  // 90 a DANGER state.
