/**
|
||
|
|
* 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.
