Every published page used to end with "Published with Vessa", a client's guidelines included. That's an odd thing to hand over. Your client paid you for their brand guidelines, and the last line of the page names someone else.
Now the publish dialog asks whose brand it is and shows only what that answer comes with. Choose A client's and the page goes live with nothing of Vessa's at the end of it. Its link preview drops vessa.design as well, on a page behind a password too.
Your own brands keep "Published with Vessa" as before. The buy dialog sells both kinds, and the dashboard shows how many of each you have ready to start. To sign a page with your studio's name, turn on the studio credit in the brand's settings.
