Time-add rules

Turn each source on/off and set how much time it adds. Rules apply live while chat is connected, and can also be triggered manually below (great for testing, or manually crediting cheer bombs / gifted sub trains).

Twitch sub/bits/follow events require EventSub with a bot/auth token, which this lightweight overlay doesn't handle on its own — chat-based fallback below listens for Twitch's own sub/gift/raid system messages in chat (no login needed) so basic sub and gift-sub time-adds work out of the box. For guaranteed bits/follows detection, trigger them with the manual add box or wire up StreamElements/Streamlabs to POST to this page's window.postMessage API (see console for docs once connected).
