THESIS: Zup begins with the blank-caption problem and proves its photo-to-caption workflow immediately; cross-posting is the finish, not the headline. OWN-WORLD: Porcelain editorial fields alternate with graphite proof stages; gold marks the brand while real iPhone captures carry every product claim. STORY: Choose photos, receive a voice-matched caption, tune it, preview each destination, then post only when ready. FIRST VIEWPORT: A large caption-first promise and App Store action sit beside one live iPhone screen with a tactile twelve-screen reel. FORM: Device-as-stage, established Zup marketing world, seed e65ccae8. FINISH: unreviewed and undocumented is unfinished; this build ends with the finish review, the verdict, DESIGN.md, and every shipping raster carrying its provenance.
