Date Range Picker

Range field with an anchored dual-month calendar panel, bound to DateTimeRange.

DateRangePicker composes DateRangeField and DateRangeCalendar in a click popover. See See the crate README for when to pick range pickers vs fields.

• Flight or hotel booking flows that need a visible calendar span
• Report filters where users pick start and end days in one control

• Wrap the tree in DatetimeLocale when timezone or format vary.
• Bind Option<DateTimeRange> through DateRangePickerBind.
• Document the feature with DatePickerFeatures::RANGE_PICKERS — there is no runtime license check.
