// accordion logic). getIncludingNodes always forces the selected config's

// a manual click into a *different* category - the forced root keeps
// reappearing and evicts the one the user just opened. Once the user has
// manually opened a root, drop any other root from the forced set so
// their choice sticks; nested (non-root) ancestors are unaffected.
