Testing checklist:
1. Each widget should render independently with its own Shadow DOM
2. Language and word length selectors should update the "Play" button link
3. Light and dark themes should look correct
4. The narrow container widget should still be usable
5. Footer links should open a2zwords.com and wordlewonk.com in new tabs
6. No CSS conflicts between widgets or with this host page
