- New /demo flow (no login/backend): take/pick a photo → card front; swipe → back reveals QR + name/title. Built in-memory on device. - CardFace renders image backgrounds (local URI or asset key) + borderRadius prop - CardViewer `fullScreen` mode fills the device window (useWindowDimensions), radius 0, status bar hidden; applied to the demo and the real card viewer - Landing screen offers the demo without signing in - Added expo-image-picker (camera/photo perms); pinned expo-constants/expo-linking to SDK 51 (npm had resolved newer-SDK majors that broke the Gradle build) - Native android/ is gitignored (regenerated by `expo prebuild`) Built and deployed to a physical Android device (BUILD SUCCESSFUL).
