"""config -- make it yours, one file, live.

C-a e opens the config in an editor pane. Every edit lands the moment it is
saved: the theme flips from pink to green, `padding` pushes the content off
the frames, `compact true` swaps floating boxes for shared dividers. (The
headless recorder asks for the reload the file-watcher would do live.)
