What is the share modal that pops up after I publish an event?

When you publish an event for the first time, a share modal opens with a one-click Copy link, a downloadable QR code, and prefilled SMS, email, Twitter/X, Facebook, and LinkedIn share buttons. Sharing in the first 24 hours drives roughly 5x more sign-ups than not sharing, so we make it one tap away. It fires once per event and never repeats on re-publish.
