v1.5.28

🐛 Fixes

• <DateRangePicker> — the second click now always registers (FW-17 follow-up). Picking the
  first date worked, but the second click often did nothing: while you moved the pointer toward the
  end date, each hover rebuilt the whole day grid, so the day cell under the cursor was replaced
  mid-click — the mousedown landed on the old node and the mouseup on the new one, and the
  browser never fired a click. The hover preview now re-decorates the existing day cells in
  place (a new shared refreshDays() on the calendar core) instead of rebuilding them, so cells
  keep their identity and real clicks always land. Also stopped the value-sync effect from
  re-rendering on hover (it was tracking the pending/hover signals through the day-cell decorator —
  now runs untracked). <Datepicker> is unaffected. Pinned by a regression test that drives a real
  mousedown → hover → mouseup and asserts the cell is never detached.
