/**
 * When to use a **range slider** vs text contains for column filters.
 *
 * | Use `range` | When |
 * |-------------|------|
 * | `cellKind: "progress"` | Fixed bounded domain (0–100 %) |
 * | `cellKind: "currency"` / `"numeric"` | Numeric column — min/max from dataset (`dataBounds`) unless `rangeMin`/`rangeMax` set |
 * | Explicit `filter.type: "range"` | Hub declares numeric band filter |
 *
 * Override back to text with `filter: { type: "text" }` when free-form match is intended.
