## 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
