+/**
+ * Render the built party-board card under jsdom and print its plates.
+ *
+ * Usage: node render-party-board.mjs < spec.json
+ *
+ * The spec JSON carries {bundle, tag, config, hass}; stdout receives one JSON
+ * object {plates, html} where plates is the ordered plate list the shadow DOM
+ * renders (name + present/away/unknown kind). The Python panel tests drive
+ * this harness so the assertions run against the exact bundle HACS ships.
