Support posts and feed items

Support feed items can show public supporter messages and purchase context when the buyer chooses to post or share. A buyer can also choose to make a shop purchase or commission public without writing a message.

Supper can also show related Bluesky or AT Protocol social posts, replies, and original-post links when a supporter or creator shares support publicly. Those social posts are governed by the service where they were posted, such as Bluesky, even when Supper displays them as part of a support feed.

Guest purchases can have Supper-owned feed items where appropriate, but they cannot write payer records to a guest's PDS because the guest does not have one.
