DurationRelativeTo
DurationRelativeTois a structural type that appears in public signatures. It is not directly importable.
The anchor date a calendar-unit duration operation resolves against, as accepted by Temporal’s relativeTo option (Duration.prototype.round/.total, Duration.compare). Years/months/weeks have no fixed length, so any operation touching them needs a starting point; day/time-only operations do not.
