-- These groups are for the neovim tree-sitter highlights.
-- As of writing, tree-sitter support is a WIP, group names may change.
-- By, most of these groups link to an appropriate Vim group,
-- TSError -> Error for example, so you do not have to define these unless
-- you explicitly want to support Treesitter's improved syntax awareness.
