View Projections

Core exports buildMonthView, buildWeekView, and buildDayView. Each projection infers its own item type, so one controller can support unrelated query results.

const month = buildMonthView({
  calendar,
  items: summaries,
  getDate: summary => summary.date,
})

const week = buildWeekView({
  calendar,
  items: events,
  getDate: event => event.startsAt.toPlainDate(),
  getStart: event => event.startsAt,
})

Calling a projection without items returns a data-free grid and needs no accessor or fake item type.
