v1.5.27

✨ Features

• <DateRangePicker> — pick a start/end date range (FW-17). A new
  @weave-framework/ui/date-range-picker: an underline trigger field showing start – end plus the same
  calendar popover as <Datepicker> (day → year → month drill-down, one month at a time). Selecting a range
  is two clicks — the first sets the anchor, the second completes it (the ends are ordered for you, so
  clicking before the anchor just makes it the new start); while you pick the end, hovering previews the
  span (a tinted band with a dashed ring on the tentative end). The value is a DateRange —
  { start, end } of local-midnight Dates — bound the usual two ways (value + onChange, or a forms
  control (Field<DateRange>)). Supports min/max/dateFilter, firstDayOfWeek (default Monday),
  translatable labels, a configurable separator, clearable, and full keyboard nav. Closing the popover
  before the second click discards the half-picked range.

🔧 Internal

• Shared headless calendar engine. The three drill-down calendar views (day/year/month grids, ‹/› nav,
  view-switch header, roving focus, full keyboard) were pulled out of <Datepicker> into a reusable
  createCalendarView core + a prefix-parameterised calendar() SCSS mixin, so <Datepicker> and
  <DateRangePicker> share one engine and one visual with zero duplication. <Datepicker> is behaviourally
  unchanged (its full test suite stays green).
