14The date picker **composes `llimphi-widget-calendar`** rather than
15reimplementing a grid: it inherits min/max limits, range selection, year jump
16and the key map. The time picker is a grid of hours plus a grid of minutes by

22`formatear`/`parsear`/`mover`/`al_paso` in 24 h or AM/PM. All pure and testable.

llimphi-widget-datetime-picker

Date and time pickers.

Both share the shape of any native picker: a trigger in the form, showing the formatted value (or the placeholder when empty) and emitting a Msg when clicked, and a popup the host mounts in App::view_overlay, with a scrim that dismisses on outside click.

The widget keeps no state: the value, whether it is open and —for dates— the focused month live in the caller's Model. That is what lets the same picker serve a form, a table cell or a filter.

The date picker composes llimphi-widget-calendar rather than reimplementing a grid: it inherits min/max limits, range selection, year jump and the key map. The time picker is a grid of hours plus a grid of minutes by step — no scrolling, no extra state, which is what a compact picker needs.

What belongs to this crate is formatting and parsing, which is where a picker becomes usable or not: formatear_fecha / parsear_fecha (ISO and day-first, with -, / or .), and Hora with formatear/parsear/mover/al_paso in 24 h or AM/PM. All pure and testable.
