Some customers use our deployment appearance options to rebrand the UI. If their users receive an email from Coder when the platform has been cosmetically changed, they may block the unfamiliar source.

We should pull from the deployment appearance and display it in the email like so:

Oddly, we suggest a logo with a 3:1 aspect ratio alongside the deployment name. Maybe we should only use the logo in the email, as some customers may include text in the image.

This doesn't block experimental but should be included in GA.
