 * MUI, react-aria all hand back the host date object). The shape narrows by the
 * configured `unit × mode`, like react-day-picker's `mode`-discriminated
 * `onSelect`: a single point is `Date | null`, a span is `{ start, end }`, and
 * the "many" cardinalities are arrays of those. Empty is `null`, never an empty

 * conditional types over optional flags.
 *
 * `value` always carries the LOGICAL spans (the user's anchor→end intent), never
 * the segmented result. Excluded-day segments are derived data and ride along in
