2-- │ Built-in Neovim behavior │
3-- └──────────────────────────┘
4--
5-- This file defines Neovim's built-in behavior. The goal is to improve overall
6-- usability in a way that works best with MINI.
7--
8-- Here `vim.o.xxx = value` sets default value of option `xxx` to `value`.
9-- See `:h 'xxx'` (replace `xxx` with actual option name).
10--
11-- Option values can be customized on per buffer or window basis.
12-- See 'after/ftplugin/' for common example.
13
14-- stylua: ignore start
15-- The next part (until `-- stylua: ignore end`) is aligned manually for easier
16-- reading. Consider preserving this or remove `-- stylua` lines to autoformat.

98-- Diagnostics ================================================================
