--
-- Dynamic Omarchy Unlocks Menu for Elephant/Walker
--
-- A "Default" entry restores the omarchy-shipped Plymouth via
-- omarchy-plymouth-reset. After that, every theme that has a preview-unlock.png
-- appears as a customised unlock; picking one runs omarchy-plymouth-set-by-theme
-- <theme>. Both run in a floating terminal so sudo can prompt.
