/* Services disclosure: a real <button> toggles .is-open on click, and native
   button semantics mean Enter/Space already fire that same click for
   keyboard users — no :focus-within needed. (An earlier version used
   :focus-within as a belt-and-suspenders opener, but that fights the
   Escape-to-close behavior: closing moves focus back to the trigger
   button, which re-satisfies :focus-within and reopens the menu right
   after JS closed it. classList is the single source of truth instead.) */
