All four services now share one builder stage (dependencies compile once per deploy, not once per service). BuildKit cache mounts keep the cargo registry and target/ between deploys: a one-line change rebuilds in ~16 s instead of recompiling the whole dependency tree.

# One Dockerfile for every backend service. Build context must be backend/
|
|
# (the workspace root). Pick a service with `target:` in docker-compose.
|
|
#
|
|
# Why one file: all four services share one `builder` stage, so the dependency
|
|
# tree (aws-sdk, sqlx, tonic, ...) is compiled once per deploy instead of once
|
|
# per service. The BuildKit cache mounts keep the cargo registry and target/
|
|
# between deploys, so a source change recompiles only the crates that changed.
