Documented steps
cd into the Compose project directory.
Run `podman compose config` to validate the file and print the fully normalized/merged configuration (environment, volumes, networks, ports).
Use `--quiet` (`-q`) to only validate and exit non-zero on error, ideal for CI.
Inspect specific sections with flags like --services or --volumes as supported by the provider.

Known gotchas
The command surfaces YAML/schema errors early — run it before `up` to catch bad service definitions cheaply.
Because podman compose delegates to a provider, the exact output/validation strictness depends on docker-compose vs podman-compose.
Podman's pod-based networking means the printed network name/resolution differs from Docker: rely on the provider's resolved output, and verify service-to-service DNS (often via localhost) rather than assuming container hostnames.
Config interpolation uses .env in the project dir; a missing variable may render as an empty string or fail depending on provider strictness.
