-- usability in a way that works best with MINI.

-- Here `vim.o.xxx = value` sets default value of option `xxx` to `value`.
|
|
-- See `:h 'xxx'` (replace `xxx` with actual option name).

-- Option values can be customized on per buffer or window basis.

-- See 'after/ftplugin/' for common example.

-- The next part (until `-- stylua: ignore end`) is aligned manually for easier
|
|
-- reading. Consider preserving this or remove `-- stylua` lines to autoformat.
