+```lua $TYP: ../lua/bars/types/statusline.lua, from: $TYP, class: statusline.config
+--- Statusline configuration table.
+---@class statusline.config
+---
+---@field force_attach? string[] List of `statusline` values to ignore when attaching.

+---@field ignore_filetypes string[] Filetypes to ignore when attaching.
+---@field ignore_buftypes string[] Buffer types to ignore when attaching.

+---@field condition? fun(buffer: integer, window: integer): boolean Additional condition for attaching to windows.

+---@field default statusline.style Default style.
+---@field [string] statusline.style Named style.
