config.json

Where brothy keeps its settings and what each key does.

~/.config/brothy/config.json (or $XDG_CONFIG_HOME/brothy/config.json when that is an absolute path) holds:

Key	Value
`ai`	see AI
`theme`	a theme name, or a family’s: `"one"` opens `one-dark`. A name brothy does not know is reported at start and `brothy` stands in
`sidebar`	`{ "view": "files", "hidden": false }`: the panel view and whether it is hidden
`wide`	boolean, full-width text (`w`)
`transparent`	boolean (`T`); `--transparent` wins for one run
`minimap`	boolean, default `true` (`m`)
`headings`	`"classic"` (default), `"bars"`, `"ladder"` or `"rules"` (`#`; Heading styles)
`motion`	boolean, default `true`; `false` draws the welcome page still, without its ink-in and steam
`zen`	the zen settings

{"theme": "dracula", "sidebar": {"view": "files", "hidden": false}}

sidebar replaces the old folds; existing folds are migrated once and dropped on the next save.

The file is rewritten when you pick a theme, change the panel view or save zen settings, keeping other keys; a file that does not parse is left untouched.
