// AC-13 for #157. Usage:
//   node demo/downgrade_open_passage.mjs --bundle=/absolute/v1.64.0/dist/houseplan-card.js
// The v1.64.0 frontend does not understand `passage`; this executable fixture
// pins its documented best-effort fallback (door symbol) and, critically,
// rejects any pageerror/unhandled exception while reading the newer literal.
