The landing page's QR card now carries a link to `GET /api/photos/:id/preset.recipe`, so the app can pick a look up off a screen instead of a file. PRESETS gains a SCAN QR chip next to IMPORT: the code is decoded, checked against the preset route, fetched, and stored through the same `storeImportedRecipe` path IMPORT already uses, so an imported look and a scanned look land in one place. Scanning runs on `expo-camera`, not the viewfinder's vision-camera: v5's object output is iOS-only, Android's `createObjectOutput` throws. That is a second camera library in the app, so the sheet pauses the viewfinder (`paused` prop) — CameraX will not let two clients hold one lens. A native rebuild is required for the new module. The code holds a URL, never the recipe, so anything that is not the preset route is refused by name rather than silently dropped. On a release APK the plain-HTTP link is blocked by Android's cleartext policy; debug builds have it on. Noted in 7_SCAN_QR.md along with the web side, the regex, and the paused-viewfinder rule.
The file is empty.
