internal/household provides Today, WeekStart, WeekDays, WeekLabel,
PeriodKey and LocalTime, all in the household IANA zone and never the
process zone. Weeks are ISO Monday to Sunday; calendar arithmetic runs
on UTC midnights so DST never shifts dates.
LocalTime reads a skipped or repeated wall time with the UTC offset in
effect before the transition: a spring-forward gap moves forward by its
length, and a fall-back repeat is its first occurrence.
store gains LocalDateOf and LocalDate.Date so household builds dates
without reparsing, and LocalDate.Value rejects years outside 0000-9999.
