/**
 * Import the built bundle into jsdom and generate the dashboard strategy's

 *
 * Usage: node render-strategy.mjs < spec.json
 *
 * The spec JSON carries {bundle, url, config, hass}; stdout receives one
 * JSON object {views} — the strategy output's views array with the paths
 * and card configs the generated dashboard renders.  The Python panel
 * tests drive this harness so the assertions run against the exact bundle
