Composite one or more app screenshots into a drawn device frame (rounded bezel, Dynamic Island on phone-shaped canvases) with a gradient background and optional headline/caption text, and export as PNG at any/all of the 4 official App Store Connect sizes. A blank page (image omitted) draws no device, for a title card or an outro. A device positioned past the edge of its page is drawn spilling onto the neighbouring page too, so a set can run one screenshot into the next. LIMITS — this runs on a small shared host, so an over-limit call is refused immediately, before any rendering, with a message saying how to split it: at most 10 pages at any one size, 2 at size:"all" (which renders every page 4 times over — a longer set needs one call per size); at most 12 rendered PNGs per call (pages x sizes); 6 MP per screenshot and 4 MB of screenshot bytes summed across the whole call (send JPEG, not PNG, for a multi-page set); and at most 40 text layers of 512 characters each.
