Checking ticket-email copy after grouped-email template changes

[awslew]

The recent grouped-ticket email work and organizer email editor make expected-content checks relevant here. I'm the maker of InlinerAPI.

If you maintain these emails, could you try one independently expected event instruction or CTA host/path rule on final rendered HTML? Free, no signup; synthetic values only: https://inlinerapi.netlify.app/requirements

Please share the actual result and setup/maintenance cost versus existing tests. If useful regularly, what would justify paying?

Standalone checker, not a Hi.Events integration: no Liquid execution, ticket/payment validation, send-trigger, delivery or inbox-appearance testing. Thank you.
