/**
 * Render the built quest-log card under jsdom and report its location.
 *
 * Usage: node render-quest-log.mjs < spec.json
 *
 * The spec JSON carries {bundle, url, config, hass, idle_ms?, probe_ms?};
 * the card is mounted at the given URL (it resolves its child from the
 * pathname's last segment), after the optional probe wait one snapshot of
 * the render is taken mid-wait, then after the optional idle wait stdout
 * receives one JSON object {location, headline, countdown, html, tiles,
 * probe, tap} — the final window pathname, the rendered title, the
 * complete-screen countdown text, the rendered shadow DOM, each quest
 * card's icon tile, and the probe snapshot when probe_ms was given. With
 * tap_complete: <instance id> the harness taps that card's Complete button,
 * records whether the confirm dialog opened, taps the dialog's Complete, and
 * reports every hass.callService call as tap: {dialog_opened, service_calls}.
 * With tap_return: true the harness taps the header's return control and
 * reports it as returned: {rendered, label} before the final snapshot.
 * With now: <ISO instant> the card's clock is pinned there (argument-less
 * new Date() and Date.now() return it; the process TZ decides its local
 * wall time), and with advance_to: [<ISO instant>, ...] the clock moves to
 * each instant in turn and the card's own 60 s clock-tick callbacks fire,
 * one snapshot per instant reported as ticks (the top-level snapshot is
 * taken before the clock moves).
 * The Python panel tests drive this harness so the
 * assertions run against the exact bundle HACS ships.
