/**
 * The dock shell's variant key — the WAAPI height-morph trigger. Pinned
 * after the practice-fold fix (owner, 2026-10-06): the expanded term
 * belongs to every docked variant, so a practice dock's fold/unfold
 * morphs exactly like a teaching question's. Before the fix the key
 * read `pending ? expanded : "-"` — pending is null in practice, the
 * key never changed on the fold, and the practice dock's height jumped
 * instantly between form and bar while teaching morphed.
