Two asks, one row of the studio each. The first is copy: a band under the header, the same shape the verify bar below it takes, saying which features are on trial, on whom, and until when. It is a notice and not a task, so it wears the plain surface rather than the accent, and it carries no dismiss: the date is the message. The string is in the dictionary like every other, Vietnamese as written and English beside it — the band is one line at both lengths in a 1440-wide window, and it sets no nowrap, so a narrow window wraps it rather than cutting it. The second is the WB panel's presets. They were a wrapping strip of seven identical pills, which is the wrong shape for one kind of value read against the others: nothing about "SHADE" said 7500K, and nothing about the row said which end of the scale anything was on. They are a TABLE now — two columns of buttons, laid out as a grid — and each button is painted with the cast it puts on the frame: the same swatch the TEMPERATURE ruler already prints under its track (temperatureSwatch, the engine's own gains on a mid grey, halved), so the button and the ruler cannot disagree, and the kelvin is printed on the button beside the name. A button that is a swatch cannot use the theme's text colour for its label: the fill is a mid grey by construction, and mid grey is exactly where white and the light theme's near-black both sit near the 4.5:1 line. So the label is given the ink that fill can carry, chosen by WCAG's relative luminance against black and against white — whichever of the two ratios is larger, which is the one that cannot fall under 4.5:1. The border is that same ink, which is what makes a button stand out from the page it sits on and from the six beside it; the accent takes the border over while the preset is the one in force, since the fill can no longer say so. Both the fill and the ink ride in as inline styles — they are the value, not the theme — so the chip needed two fields and a tinted class, and the row needed a grid mode. The TEMP strip reads the same two fields through choiceChips, because the same seven presets are painted in both places and two opinions about 3200K is the bug this would have been. The chip's own value slot is deliberately unused here: `.chip .val` sets its own dim colour, and a dim grey on a mid grey button is the failure this commit is about. Verified: scripts/wb-table-check.mjs — readableInk picks the better of its two inks for black, white and four mid greys, all 151 swatches across the ruler (2500..10000K, every 50) and all seven presets clear 4.5:1 under the ink they are given, the swatch runs the way the ruler does (red up, blue down, #517eff at 2500K to #947d61 at 10000K), and the seven presets collapse to the five fills their kelvins do. In the running app through a probe: the notice prints in both languages (Vietnamese one line, unclipped), 7 buttons in a 147px + 147px grid, TUNGSTEN filled rgb(98,130,187) with ink rgb(11,14,18) and a 2px border of the same, AUTO the accent border rgb(206,117,9) while it is the preset in force, and the panel holds at 420px wide without overflowing. The panel was viewed in both themes. npx tsc --noEmit clean, npm run build clean. Co-authored-by: PenguinHarness <noreply@penguin.local>
RecipesCam web — self-contained stack
A Docker-hosted web build of RecipesCam. Everything it needs is in this folder: move it to another machine, run two commands, and the app is up. It does not need the React Native project around it.
cp .env.example .env
docker compose up -d --build
# → http://localhost:8090
What runs where
| Service | Image | Role |
|---|---|---|
frontend |
nginx:1.27-alpine (built by frontend/Dockerfile) |
Static SPA + /api/ reverse proxy |
api |
node:22-slim (built by backend/Dockerfile) |
Accounts + saved recipes, SQLite on ./data |
frontend resolves api through Docker's embedded DNS and proxies /api/* to
it — that is why the API container is named api and why it is not published on
the host. Only ${WEB_PORT:-8090} is exposed.
Photos never leave the browser. The CanvasKit render pipeline (grade, frame, watermarks, JPEG encode) runs in the visitor's tab; the API only stores recipes as JSON.
Layout
docker-compose.yml the stack
.env.example WEB_PORT
data/ SQLite (created on first run, gitignored)
backend/ Fastify + better-sqlite3 API, own Dockerfile
frontend/ Vite + React + CanvasKit SPA, own Dockerfile + nginx.conf
shared/ vendored copies of the app's types + utils (see below)
src/engine/ skiaShim.ts (CanvasKit) + exportEngine.ts (render pipeline)
+ session.ts (localStorage/IndexedDB studio persistence)
Vendored files
frontend/shared/{types/index.ts,utils/*.ts} are byte-identical copies of
src/types/index.ts and ten src/utils/*.ts files from the React Native
project (@shopify/react-native-skia is aliased to src/engine/skiaShim.ts in
vite.config.ts + tsconfig.json, so those files compile unchanged):
cinemaShader colorUtils defaultRecipes exifWrite frameUtils jpegDpi
paramDefs recipeShare skiaImage toneShader.
The landing page needs no CDN: frontend/public/assets/fonts/*.woff2 are the
seven self-hosted faces behind the three font groups the Themes menu offers
(Plus Jakarta Sans / Inter / JetBrains Mono, Fraunces / Be Vietnam Pro /
Courier Prime, Be Vietnam Pro / Space Mono — all SIL OFL, pulled from Google
Fonts, vietnamese + latin + latin-ext subsets), and
frontend/public/assets/samples/s*.jpg are the six placeholder negatives the
film strip, preset tester and QR card show (swap them for real graded stills
whenever we have them). Its one foreign request is the QR image from
api.qrserver.com, which degrades to an empty slot offline.
When the app changes one of them, copy it back in — the renderer is only "parity" for as long as these stay in sync:
cd <repo>/docker/frontend/shared/utils
cp <repo>/src/utils/<name>.ts .
Operations
docker compose logs -f api # API log
docker compose restart api # after backend/src changes (rebuild: --build)
docker compose down # stop; ./data survives
Backup is the ./data folder — that is the whole database.
Checks
curl -s http://localhost:8090/api/health # {"ok":true}
curl -sI http://localhost:8090/ # 200, index.html
Then open the UI, drop a photo in, and confirm the preview shows the picture and
EXPORT downloads a JPEG that opens. The preview going solid black while the
export still reports a plausible size is the one failure mode worth knowing: it
means the CanvasKit GPU surfaces lost their shared GrDirectContext (see
frontend/src/engine/skiaShim.ts), and with no GPU the raster fallback renders
the same pipeline correctly, just slower.
