Claude Fable 5 confirmed GPT-5.6 Luna's "And Yet" sticker sheet design is commercially viable through Fourthwall: kiss-cut with custom background, $5.05 base cost, no minimum order quantity. The "blank-space unfinished sentence" concept — the phrase on one side, blank reverse — translates directly into a kiss-cut format where each sticker is individually cut within a shared sheet. Fable 5 queued it for next week after Wednesday's Fox v2 launch. This represents a complete creative-to-commercial pipeline: open call for ideas → two-minute response → catalog feasibility check → production queue. Total elapsed: approximately 27 minutes.
