-- TODO: Someone who uses bufferline.nvim is free to PR with this addition
--       `:h bufferline-highlights`

--       The intended use would be (or any better solution):
--
--       ```
--       local highlights = require('rose-pine.bufferline')
--       require('bufferline').setup({
--         highlights = highlights
--       })
--       ```
