WB and FX were separate tabs whose only content was the same Lightroom-style develop column LIGHT already renders, so the rail carried three doors into one room. LIGHT now owns the whole column: white balance, tone, presence, the effects group (grain, dehaze, vignette) and the filters, in that order. The `wb` and `fx` TabIds, their rail entries, their `wbLabel()` helper and the now dead `tab.wb` / `tab.fx` i18n keys are gone; `ToolRail` documents eight tabs. Every continuous develop value that the UI exposes as a symmetric knob now runs -100..+100 instead of -10..+10. `paramDefs` gains the `HUNDRED` key set and the `deepen` helper, which widens a def's range and scales its accessors by ten, so the store keeps its -10..+10 internal scale and every stored look, DEFAULT_RECIPES entry and URL round-trip is byte-identical. Params with a meaningful physical scale (temperature in kelvin, exposure in EV-ish units, grain, grain size, hdf, vignette, rotate, crop) keep their own units. Highlight recovery no longer bends hue. The old knee clamped the per-channel gain into 0.55..1.35, which is a per-channel operation and therefore a hue rotation: on the flat skin patch it walked hue from 24 deg to 48 deg at HIGHLIGHT +100, and on a saturated 30:1 chroma ramp it desaturated toward black instead of toward white. The shader now caps the pixel's distance from its undersaturated knee point while preserving the direction of that offset, i.e. it scales chroma and keeps hue, then clamps into gamut. Verified: - `npx tsc --noEmit` clean; `npm run build` clean. - `node scripts/highlight-knee-check.mjs` (pins the new shader source and twin-tests 135 knob combinations) ok. - Existing checks re-run green: `auto-tone-check`, `half-check`, `white-level-check`, `preview-match-check`, `library-check`, `scan-nav-check`, `roll-walk-check`. - Live browser pass: rail shows exactly the seven expected tabs with no WB or FX; LIGHT renders 5 panels / 23 `data-key` knobs; 12 knobs report `min=-100 max=100`; everything else keeps its own range. - Highlight hue measured on ten flat colour patches: HIGHLIGHT -100 gives a hue delta of 0.00 deg on every chromatic patch; HIGHLIGHT +100 stays within 0.22 deg (sky) and 0.28 deg (magenta) wherever chroma survives, and the patches the ramp intentionally drives to white arrive fully neutral. Greys stay neutral (channel spread <= 2/255) at every knob setting. Skin patch before/after: 23.94 deg -> 0.00 deg. ponytail: temperature (2500-10000 K), exposure (+-10 units at 0.25 EV each), grain, grain size, hdf, vignette, rotate and crop deliberately keep their own scales rather than the blanket -100..+100; widen them the day a user asks for more range, not before. Hue assertions live in the flat-patch check because real-photo measurements pick up 2-4 deg of resample drift from the snapshot pipeline that has nothing to do with the shader.

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.
