The first version of this picker invented its own visual language — free-
standing bordered cards with a hand-rolled check — which matched nothing else
in the app. It is now the family's standard shape: FullScreenPicker with
PickerDescription and connected GroupedRows, tonal highlight and the shared
SelectedCheck.
Above the rows sits a live, scaled-down Month view that changes as you pick a
style. It renders the *real* grid composables rather than a drawing of them, so
the preview cannot drift from what it depicts: MonthGrid, ContinuousMonthGrid,
SplitMonthGrid and SplitDayPane are now internal rather than private, and the
sample month runs through the same layoutMonthWeeks/layoutCalendarWeek the live
views use. The month, today's position, week start, colour softening and clock
format are all real; only the events are stand-ins, since a settings screen has
no business querying the provider for a thumbnail.
Selecting applies immediately and leaves the picker open — closing on tap would
hide the very thing the screen is for. Back exits, as in the App name picker.
Scaling note worth keeping: Modifier.requiredSize looks like the way to force a
full-viewport measurement, but it *centres* content that overflows the incoming
constraints, which left only the grid's bottom-right corner inside the clip. A
layout modifier that measures at Constraints.fixed and reports the scaled size
has no overflow to align and no dependence on parent alignment.
PickerDescription is internal now rather than duplicated.
