This is a CSS only component that simply provides a classic "tile" layout.  A tile seems to be organized with a left side that has an image/icon, a middle with content, and a right with buttons or other things.  You don't need Svelte to make this work, and actually trying to use Svelte ends up making it more complex than just using CSS. To see how you use this just look in `admin/bando/demos/Tiles.svelte`.
