 *
 *   - `range` present (non-null/non-undefined) → treat as a date-style filter
 *       "anytime"  → inactive  (default — user hasn't filtered by date)
 *       "custom"   → active only when both start and end dates are filled
 *       any other  → active    (e.g. "today", "last7days")
 *   - no `range`   → treat as multiselect-style: active iff `values.length > 0`
