terraform.workspace drives environment-specific config💡 Analogy
Workspace config lookup is like a hotel room service menu — same hotel (codebase), but each floor (workspace) has a different menu (config).
terraform.workspace is a built-in variable with the current workspace name. Use it to look up environment-specific configuration from a local map.
