Currently, the UI Shell is not themable and only supports dark mode.
Open the following examples in a new tab to experience them in full.
## Header
## Header with side navigation
The hamburger menu will automatically be rendered if the `SideNav` component is used.
## Header with side navigation (rail)
Set `rail` to `true` on `SideNav` to use the rail variant.
## Header with app switcher
The `HeaderAction` component uses the [transition:slide API](https://svelte.dev/docs#slide); you can customize the transition duration, delay, and easing with the `transition` prop.
You can disable the `transition` by setting it to `false`.
