/* Undo and Redo in the header are wired to the diagram store alone, so a pencil
   stroke, an eraser pass or a shape left both buttons greyed out even though the
   action is perfectly undoable. history.js re-enables the real button; these
   rules restore the enabled skin the bundle only paints when the diagram store
   itself has history. The values are the bundle's own enabled classes
   (text-slate-700 border-slate-300 bg-white hover:bg-slate-100), so an enabled
   button looks identical whichever store the next step belongs to. */
