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.
- One free Play app (com.locphamtran.recipescamera) with an expo-iap PRO
unlock, replacing the paid apk for the store channel
- Android SEND/SEND_MULTIPLE share target feeds photos into the editor,
on cold start and on resume
- BACK button in the TopBar and press-and-hold PEEK replace the chip row
- NOISE REDUCTION and SHARPENING accept -10: a negative SHARPENING softens
the frame before the grain pass, a negative NOISE REDUCTION re-grains it,
in the Skia engine, the live preview and the Kotlin export path alike
Rename LIGHT GLOW to HDF EFFECT and gate it behind PRO: LITE renders the
chip greyed out with a PRO tag and cannot open its slider; restoration of
older settings that carry hdf > 0 still blocks export in LITE.
Play/licence pass:
- drop unused permissions (ACTIVITY_RECOGNITION, READ_MEDIA_AUDIO/VIDEO,
SYSTEM_ALERT_WINDOW) and requestLegacyExternalStorage
- rename the Leica sims to LC STREETLIFE CLASSIC/VIVID, drop the brand from
comments; fix app name text, canvaskit copyright, LICENSE owner
- remove expo-image-picker and expo-sensors (no JS import), delete dead
exports (computeMatrixTint, cinemaSeasonName, base64 helpers,
formatCoordinate)
- versionCode 3 / versionName 1.2.1, drop the personal email from About
- add docs/privacy-policy.html for the Play listing

Both flavors build from one JS tree: `lite` hands out the free apk
(com.locphamtran.recipescamera), `pro` sells as-is (same id + .pro, label
"RecipesCam Pro"). Release is signed from android/keystore.properties, both
files gitignored - lose either and no later build can install over this one.
The tier reaches JS through src/provariant.ts, which tools/set-variant.mjs
rewrites before each build (`npm run apk:lite` / `apk:pro`); the gradle flavor
alone would ship a Pro apk that thinks it is Lite.
The dev scaffolding goes: the three src/dev probes and their App effects, the
EXPO_PUBLIC_CAPTURE_MODE [CAPTURE] timing log, and the -PdevtestSuffix
side-by-side install hook. 'balanced' stays the shipped capture mode, which is
what those probes measured on the 12S Ultra.
Looking at the picture: WB now converts kelvin through the Planckian locus into
a luma-normalised gain (unity at 5500K, symmetric tint) instead of the old
one-sided push; LEITZ STREETLIFE splits into CLASSIC and VIVID; selecting a
recipe loads every knob it carries over the defaults and stays editable, and
RESET hands the panel back to the sim's own values. The in-app library picker,
the ultra-wide native module and recipe share/import land here too.
CLARITY and LIGHT GLOW existed only on the camera worklet and the export
engine, so a photo opened from the library ignored both. They now run in all
three library preview branches (libPhoto), and the preview clips them to the
drawn image - the export engine always clipped its bloom to the canvas, the
preview drew it over the whole rect, so the bloom bled past the photo onto the
black letterbox and over the frame's mat.
The ROTATE strip gains an AUTO chip that reads the device tilt from expo-sensors and feeds it into the straighten angle while the library is open, so the export is levelled to the horizon. It sits right after RESET, combines with the manual STRAIGHTEN offset and with the quarter turns, and both RESET paths clear it.
The accelerator is sampled every 100 ms only while AUTO is on and the library is visible; near-flat and past 45 degrees readings are ignored so the level does not chase noise. AUTO rotates the image by +roll (a +10 degree emulator tilt exports 10 degrees clockwise), which is the sign that matches the preview.
A level line overlay is drawn in the preview: amber within one degree of level, white otherwise. Adds the expo-sensors dependency, so a native rebuild is required.
