+ * Uses path-style endpoint so dotted bucket names pass TLS hostname validation.
+ * Credentials are resolved via the standard provider chain (env vars → ~/.aws/credentials).
+ * AWS returns an empty LocationConstraint element for us-east-1 (the implicit default region).
+ * Mirrors the behaviour of the `get-bucket-location` app-builder subcommand.
