cc186c4put the news about the trial into the bar, one line, and asked nothing more of it. On the landing page that line is a sentence, not a label: at 1440 it fits, on a phone it wraps into a paragraph and the bar grows a shelf of text above the hero. So the band is drawn as a track and the sentence is set in motion — one line that is never wider than the window because it is never asked to fit in it. It is the same bandcc186c4wrote, moved to the last shelf of the bar, under the menu line rather than beside the header. Two copies of the string ride the track, the second hidden from screen readers so the news is announced once, and the track slides exactly half its own width: the copy that was waiting arrives where the one before it left, so the loop has no seam and the 72px of air lives in each copy's right padding rather than between the two. `width: max-content` on the track is what makes that half-exact — the track is the two copies and nothing else, so -50% is one copy by construction and not by measurement. 40s, linear, infinite; the animation is dropped under `prefers-reduced-motion: reduce`, where the sentence simply sits at the left edge of the band, clipped the way it already is mid-scroll. The colour is the theme's own ink, not the page's amber: the notice is the product's voice about itself, so it wears the accent the rest of the landing page wears and follows the visitor through all five themes. The bare accent is too bright to read on the light theme's paper, though, and the worst pair is itself in the theme set — the bare accent lands at 4.0:1 on the violet dark page, which a 12px line may not wear. So the ink is `color-mix`ed 78% accent toward the page's text colour: the hue that says "theme colour" survives, and the value walks toward whichever extreme the page already uses, which is the one direction that is always safe. Worst pair across the ten theme/page combinations is 5.66:1. The bar is fixed, so the shelf it gained is a shelf the hero has to pay for: `scroll-padding-top` goes 116 to 148 (62px of nav + 43px of subnav + 32px of notice, plus a little air) and the hero's top padding 184 to 216. Below 1160px the subnav is gone and only the notice is owed: 144, up from 112. The numbers are hardcoded rather than measured — the bar's height is a sum of three fixed shelf heights, and a ResizeObserver watching a 32px band would be machinery that reports what the stylesheet already says. Verified: npx tsc --noEmit clean, npm run build clean. In the running app through a probe: navBottom 139.08, subBottom 105.89, notice.top 105.89 then height 32.19, so the band sits directly under the menu line; trackW 1426.625 is exactly 2 x spanW 713.312, so -50% is one copy and the loop is seamless; the transform was observed mid-flight (matrix -12.48 to -39.53 over 1.5s) with overflow hidden and the animation named; h1Top 267.59 clears navBottom 139.08, the same gap the hero had before. At 390x800: noticeTop 62, height 32.19, subnav hidden, one line, no wrap, h1Top 195.59. The band was viewed in both themes and at both widths. Contrast of the mixed ink against each page, all ten theme/page pairs, measured from the rendered pixels: 6.79 / 9.89 / 5.66 / 10.22 / 12.64 light and 10.98 / 7.69 / 12.72 / 6.76 / 5.67 dark.

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
Repository layout
App.tsx, src/ the Expo app: screens, tool rail, viewfinder, shaders
docker/ the web build (frontend + API + compose file)
frontend/shared/ vendored copies of the app's types and utils
