iframe context
The same plain HTML embed page is loaded below inside an <iframe>. The
QuestKit embed should work identically to a top-level mount — the IIFE does not depend
on cross-frame messaging, only on its own document.currentScript and the
widgets present in its document.
If you see the MissionList and CoinBalance widgets rendered inside the framed page below, iframe-embedded usage is verified.
No questkit.iife.js script tag on this outer page — only the framed
document inside the iframe loads the embed.
