The creator's corrected Starting artwork (the in-app onboarding screen: sign in → stream details → go live) replaces yesterday's version. 2724x1536 resampled to the 1920x1080 master, q3 (432 KB). The previous Gemini render is archived beside the original art. Also fixes the two reasons the replacement would not have appeared on an existing profile: - **The first heal iterated `AllBackgrounds()`**, which returns only the LIVE scene's capture rows, so it cleared nothing and then saved the version anyway — permanently skipping the heal. It now walks every scene's background. Version bumped to 4 so profiles stamped 2 or 3 heal. - **The pack URI was unqualified**, so it resolved against the ENTRY assembly: LlamaCasty.exe in production, the test host under `dotnet test`, where the seed silently did nothing. It is now `/LlamaCasty;component/Assets/…`, which works in both. Test: `BackgroundDefaultArtTests` seeds a profile, plants an "old art" asset on the Starting background, marks the layout as an older art vintage, relaunches and asserts the shipped art is re-stamped. 45 background tests pass.
