 Eight types are described so far: header, hero, body text, button, image banner, features, divider and footer. The rest are rendered by their views and edited with their Filament blocks as before, and are described one at a time. Tests check that every described field is read by its slot's view, so the description cannot drift from what is rendered.

 An editor for the slots, built as a web component with no framework: `<odden-mail-editor>`. It shows the email as it will be sent, with a palette of blocks, a structure list, and a settings panel for the selected block. Drag a block from the palette onto the email, or drag a block to move it. Every action also has a button and a keyboard shortcut, and changes are announced to screen readers. Undo and redo (Ctrl or Cmd + Z, Shift + Z) cover everything.
 
-The editor edits the slot document as data and never touches HTML. The server renders the preview with the same compiler that builds the email, so what you see is what is sent, and the preview cannot be broken by editing. Only the first eight slot types are editable so far (see the slot schema above). A slot of another type in the document is kept as it is: you can move, duplicate and delete it, and its preview is rendered.
