/**
 * Hides every child of a Solo but the one it names active.
 *
 * A Solo is a Node that shows exactly one of its children at a time — the variant switcher behind a
 * character's alternate limbs or a button's states. Without this it still imports as a plain node, so
 * all of its variants draw at once, stacked; that is a visible wrongness rather than a missing
 * feature, which is why it is applied rather than reported.
 *
 * The active child is named by a component index, verified against every Solo in the reference corpus:
 * all 9 resolve to a component whose parent is the Solo itself.
