The phone screen was painted in literals — `#101014`, `#f4f4f5` and forty more — so it stayed dark whatever theme was set: pick Light, press Mobile Cloud, and the reader is handed a black page with white ink. Every surface and ink in `styles/mobile-library.css` is now one alias (`--ml-bg`, `--ml-text`, …) that reads the theme's own tokens, the faint linings and fills are a `color-mix` of the ink at the alpha they already carried, and the amber the file already asked `var(--accent)` for is now what the star, the pressed pill and the selected frame wear too. Only the four status inks carry a light-theme override, the tokens having no word for them. The five inline dark styles left in `MobileLibrary.tsx` read the same aliases. Measured on the running container at 390×800, Light chosen on the desktop: the phone was `rgb(16,16,20)` on ink `rgb(244,244,245)` whichever theme was set; it is now `rgb(255,255,255)` on `rgb(20,24,29)` under Light and `rgb(0,0,0)` on `rgb(242,243,245)` under Dark, held through the handover and on the way back. A contrast sweep of the grid and the reader in both themes leaves nothing under 3:1 but the tick glyph, which its own box draws. `mobile-pick-check` asked for one frozen amber; it asks for the accent the app is using, which is what that outline has become.
RecipesCam
RecipesCam is a camera and photo-editing app built around recipes — reusable
looks that carry a film simulation plus a full set of adjustments. You shoot or
open a photo, dial in a look, and keep it as a recipe you can apply again, share
as a .recipe file, or save to your account.
It ships twice from one repository: a React Native (Expo) app for iOS and
Android, and a self-contained web build under docker/ that runs the same
render pipeline in the browser.
What it does
- Shoot with a recipe applied. Live viewfinder, GPS-tagged captures, and the recipe baked into the saved file.
- Film simulations. Built-in looks — PROVIPES, VELVIPES, CLASSIC CHRIPES, CLASSIC NEGIPES, ASTIPES, ETERNIPES, ACRIPES, B&W HIGH CONTRAST and the LC STREETLIFE pair — each with its own grain and tone curve.
- The full adjustment set. Exposure, contrast, highlights and shadows, saturation, colour temperature, clarity, grain, and an HSL mixer with a colour picker that samples straight off the photo.
- Geometry. Crop to a fixed ratio or free-form, quarter turns, and a straighten ruler, plus printed frames (classic border, retro instant, wall frame portrait/landscape).
- Finishing. Watermark and GPS stamp, EXIF carried through the export, JPEG written with a proper 300 DPI JFIF header.
- On-device upscaling. A Real-ESRGAN pass runs locally when an export asks for more pixels than the source has — no server sees the photo.
- Recipes. Save, favourite, export and import
.recipefiles; the web build keeps them in your account, the phone build also keeps them on device.
The two builds
| Build | Where | Stack |
|---|---|---|
| iOS / Android | repo root | Expo + React Native, @shopify/react-native-skia for the render pipeline, NativeWind for styling |
| Web | docker/ |
Vite + React, CanvasKit (canvaskit-wasm) for the same pipeline, Fastify + SQLite API for accounts and recipes |
The render engine is shared by design: the web build compiles the app's own
src/utils/* and type definitions unchanged, with @shopify/react-native-skia
aliased to a CanvasKit shim (docker/frontend/src/engine/skiaShim.ts). A look
looks the same on both because it is the same code.
Running the web build
cd docker
cp .env.example .env
docker compose up -d --build
# → http://localhost:8090
Photos never leave the browser: grading, framing, watermarking and JPEG
encoding all run in the visitor's tab; the API only stores accounts and recipe
JSON. See docker/README.md for the layout and the proxy setup.
Running the app
npm install
npx expo start # Expo Go / dev client
npx expo run:android # or run:ios for a native build
