/**
|
||
|
|
* 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, probe} —
|
||
|
|
* the final window pathname, the rendered title, the complete-screen
|
||
|
|
* countdown text, the rendered shadow DOM, and the probe snapshot when
|
||
|
|
* probe_ms was given. The Python panel tests drive this harness so the
|
||
|
|
* assertions run against the exact bundle HACS ships.
