Dockerfile.dev

# syntax=docker/dockerfile:1
#
# Dockerfile for compose / local development. Builds the SPA, builds the
# Go binary, and ships it in a distroless static image. Slower than the
# goreleaser-shaped Dockerfile (which expects a pre-built binary), but
# self-contained: `docker compose build` Just Works.
