/**
 * 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, url?, click_plate?};
 * stdout receives one JSON object {plates, tappable, location, html} where
 * plates is the ordered plate list the shadow DOM renders (name +
 * present/away/unknown kind), tappable the plate names rendered as tappable
 * <button> plates, and location the window pathname after the optional plate
 * tap. The Python panel tests drive this harness so the assertions run
 * against the exact bundle HACS ships.
