* The three shapes the DatePicker emits, and what a page must do with them.
|
|
*
|
|
* The bug: the Deliveries page ran every emitted value through
|
|
* `dayjs(d).format('YYYY-MM-DD')`. For a range preset that is
|
|
* `dayjs({ from, to })` and for All Dates it is `dayjs('all')` — both Invalid
|
|
* Date — so the filter compared every row against the string "Invalid Date".
