// docker-bake.hcl — Declarative multi-image build configuration
// All sandbox image variants built in a single `bake` invocation.
// Bake builds targets in parallel, deduplicates shared base stages.
//
// Usage:
//   TAG=pr-42 SANDBOX_VERSION=0.1.0 docker buildx bake main
//   CACHE_REPO=ghcr.io/org/repo/cache TAG=main docker buildx bake main
