3. Subcommands — enum-driven subcommands, nesting, renames, global flags
4. Config Files — JSON/JSONC, search paths, custom formats
5. Environment Variables — prefixes, nesting, aliases
6. Layered Configuration — the builder, the driver, merge precedence
7. Defaults & Optionals — what is required, what is not
8. Environment Substitution — ${VAR} interpolation

10. Help & Completions — --help, --html-help, --version, shells
