- Multi-stage build: Node builds the frontend, Go builds a static CGO-free binary, runtime is Alpine with CA certificates - Add docker-compose.yml with persistent volume for the SQLite database - Add .dockerignore to keep the build context slim - Embed time/tzdata in the Go binary for OS-independent timezones - Document image build, startup, secrets, and reverse-proxy setup in README
