Part of #1

Question

Design the Docker setup for the single-container bookshelf app. Key decisions:

Multi-stage build: Build stage (Go compiler) → runtime stage (distroless/alpine/minimal)
Runtime image: Which base image? (gcr.io/distroless/static, alpine, debian-slim)?
Static assets: How to embed templ-generated HTML and PicoCSS into the Go binary? (go:embed?)
Database persistence: Volume mount for the SQLite file so data survives container restarts
Entrypoint: What command runs the server? Any health check?
Build context: What gets copied into the image? (Only compiled binary + embedded assets, or the whole repo?)
docker-compose: Single docker-compose.yml or just Dockerfile + run command?

The goal: a minimal, secure, fast-starting container.
