The Flutter SDK image is ~2.8 GB and filled Docker Desktop's VM disk
("read-only file system" while extracting a layer). Build the web bundle
on the host instead and COPY client/app/build/web into the 2-stage
(NestJS build -> slim runtime) image. .dockerignore keeps the bundle,
drops the platform scaffolding. README documents the host `flutter build
web` prerequisite.

- Dockerfile: 3-stage — Flutter web build, NestJS build, slim node runtime.
Runtime copies dist + node_modules + prisma + the web bundle
(WEB_CLIENT_DIR=/app/web), runs `prisma migrate deploy` then `node
dist/main.js`. One container serves client + API on :3000.
- docker-compose.yml: postgres:16-alpine with a healthcheck + the api
service; config from backend/.env (Compose v2 strips quotes),
DATABASE_URL + GOOGLE_APPLICATION_CREDENTIALS overridden for the
container, serviceAccount.json bind-mounted read-only.
- .dockerignore keeps node_modules/build/secrets out of the context.
Not run here (no Docker on this box); the stack also runs natively against
the local Postgres.
