Poster sessions let customers leave the create flow and come back later. During creation, configuration can be stored locally in the browser, while verified email sessions can also be saved to Supabase for recovery across devices. A saved session can include selected style, crop, size, frame choice, prompt, reference images, and generated result depending on where the customer is in the flow. For best results, customers should verify their email before closing the browser and use the same email when returning. On the same device, local storage can often restore active work. On another device, email verification and a resume link or session list are needed. Generated assets may not be stored forever, so customers should complete checkout once happy.
