Is this official YouTube A/B testing?
No. ThumbBattle is for pre-publish previewing and voting. It does not split real YouTube traffic or modify live videos.
Do I need a YouTube API key?
No. The core flow uses mock competitor/feed data. A YouTube API key can be added later for optional competitor lookup.
Do voters need accounts?
No. Public voting links work without login, with simple localStorage duplicate-vote prevention.
