Localstack + tflocal for Dev

Localstack mocks AWS locally; tflocal is the Terraform wrapper.

Idea

Run Terraform against a local AWS mock. No cloud cost; fast iteration.

Useful for development and PR validation.

Mock has gaps. Some services not implemented; some behaviours simplified.

Final validation still needs real AWS.

CI: pre-flight tests against Localstack.

Catches Terraform errors before real apply.
