## Best for

A community feed layout under a full width search header, with Custom Feed and Communities groups and a Manage Feeds filter menu

## Agent notes

- Replace `SIDEBAR_SECTIONS` and `USER` in data.tsx; the Custom Feed group holds New order received and New customer registered sample rows
- `HeaderSearch` has no submit handler, and the `HeaderToolbar` buttons and every Manage Feeds item in `Toolbar` have no click handler
- Render your feed inside `CommunityDashboard`, which holds only dashed placeholder cards under its toolbar

## When not to use

- A black icon rail beside a second nav column, under a page title header: use [Dual Sidebar Dashboard](https://web.dev.reui.io/blocks/application/app-shell/app-shell-16.md) (`get_block("app-shell-16")`)
- Account settings forms switched from a grouped sidebar, such as billing and API keys: use [Account Settings Hub](https://web.dev.reui.io/blocks/application/profile/profile-9.md) (`get_block("profile-9")`)

## 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
