/**
 * Document vault — the procedure filter.
 *
 * The facet beside the condition filter: it lists the procedures that hold a
 * document, labelled the way the visits page heads them, narrows the list to
 * one procedure's documents through the real `encounterId` filter, writes the
 * choice to the URL (`?encounter=`), comes back from a deep link, and clears
 * with the one clear control. Run at a 1440 px desktop and a 390 px phone,
 * where the filter row must stay a single line with no sideways scroll.
 *
 * Fixture: `ensureProcedureFixture` (two procedures over a namespaced trio of
 * documents), upserted before every test because the visits spec clears the
 * account's visits; the dates sit far outside that spec's ±7-day window.
