<baht-datepicker>

Calendar picker (flatpickr, reskinned on the tokens: tinted header band, round day cells, Today / Clear footer; never the OS date wheel). Value is ISO yyyy-mm-dd — one string, a [start, end] range or a string[] by date_mode. min/max, disabled_dates and disabled_weekdays grey days out (and grey out Today) and the engine enforces them on validate.
