Theme Examples

An example plugin to read, copy and change: twenty animated backdrops behind the chat in the desktop app, with frosted-glass panels: one per project or per session. /custom-theme list names them. Fireworks go off over the theme when Claude says "merged"; /fireworks sets them off by hand.
