// Standalone tests for the deferred FX-park queue's re-entrancy rule — no
// REAPER, no test framework.
//
// The property under test: a mode switch leaves its per-FX offline work here, so
// a second switch arriving before the first drained must leave every track in the
// state the SECOND switch specifies — never the first's, never both replayed.
