Enum: PrevalenceClassEnum

Coarse, always-fillable band for disease occurrence — the population-rate analog of the HPO-style FrequencyEnum used for phenotype frequency. The numeric bands are the Orphanet prevalence classes (so the ~7% of records already quoting Orphanet map directly and the ICEES/ORPHA structured sources stay aligned); the qualitative tiers cover records that report only prose ("rare", "common") with no numeric estimate. When a numeric estimate exists, also populate rate_per_100000 (or rate_low/rate_high); the band is the queryable summary, the rate carries the precision.

  COMMON:
    text: COMMON
    description: Qualitative tier for disorders described as common/endemic with no
      numeric estimate captured. Roughly corresponds to the >1/1,000 region but asserted
      only qualitatively.
    title: Common
  RARE:
    text: RARE
    description: Qualitative tier for disorders described as "rare" in the source
      without a numeric estimate (the EU rare-disease threshold is <1 in 2,000).
    title: Rare
  ULTRA_RARE:
    text: ULTRA_RARE
    description: Qualitative tier for disorders described as ultra-rare / only a handful
      of reported cases, with no population rate available. Often paired with measure_type
      CASES_IN_LITERATURE.
    title: Ultra-rare
  NOT_YET_DOCUMENTED:
