focus_mode.lua

-- focus_mode.lua
-- A plugin that combines visibility toggles, text overrides, and custom
-- components to create a "focus mode" — hiding the sidebar, relabeling the
-- header, and injecting a motivational quote at the bottom of the screen.
-- Toggled on/off with a single keybinding.
