16 built-in themes. An operator's own, uploaded under Customization, sit beside them in the picker.
Before signing in
The sign-in card has a light-or-dark button in its corner, which swaps the two Yeetline themes and is kept the way any choice is.
The operator's own
An operator can upload themes under Customization and make one the default for new visitors; anyone who has chosen a theme keeps their choice. /theme in the message box lists what this server has; /theme cerulean switches.
Your email wears it too
The email this server sends you — a sign-in code, a notice — is drawn in the theme you picked, and a new pick reaches your next letter. The app tells the server the theme's name and nothing else. Until you pick one, your email wears this server's default.
