## Best for

A month picker in an inset sidebar that slides fully away, with the next 2 events and Events, Meetings, Tasks and Reminders counts

## Agent notes

- Replace `SCHEDULE_EVENTS`, `CALENDAR_MENU_ITEMS`, `CALENDAR_ACCOUNTS` and `USER` in data.tsx with your own events, calendars and account
- The header month title formats `DEMO_REFERENCE_DATE`, not `selectedDate`, so picking a day in the sidebar never changes it
- `activeView` only relabels the view menu, and Today, New Event and the period arrows have no handler; render your view in place of the `Card` grid

## When not to use

- A working week grid with drag, resize and full CRUD beside the mini month picker: use [Mini Month Calendar](https://web.dev.reui.io/blocks/application/event-calendar/event-calendar-2.md) (`get_block("event-calendar-2")`)
- A month picker beside a day agenda that filters by status, in one card: use [Appointment Planner](https://web.dev.reui.io/blocks/application/schedule/schedule-1.md) (`get_block("schedule-1")`)

## About App Shell blocks

### When to use

- The outer layout of a multi page product: the navigation around its content area
- Dashboards and admin consoles that switch between workspaces or projects

### When not to use

- One overview page of stats, charts and tables inside your own layout: use the [Dashboard blocks](https://web.dev.reui.io/blocks/application/dashboard.md)
- A top bar on its own, above a page layout you already have: use the [Navbar blocks](https://web.dev.reui.io/blocks/application/navbar.md)

### Agent notes

- Shells that switch themes call `useTheme` from next-themes, so the app must mount the next-themes ThemeProvider
