 * CalendarDate — pure proleptic-Gregorian calendar day.

 * No JS `Date`, no timezone, no DOM. A `CalendarDate` is a plain wall-calendar
 * coordinate: "the 5th of June 2026", independent of any clock or zone.
 *
 * Non-Gregorian calendar systems (Hijri, Hebrew, Japanese) are out of scope for
 * v3. If ever needed, they arrive via a separate `CalendarSystem` adapter, not
 * by reinterpreting these fields.
