python-configuration

Centralized, typed configuration management using environment variables and pydantic-settings. Externalize configuration from code using environment variables and typed settings. Well-managed configuration enables the same code to run in any environment without modification. All environment-specific values (URLs, secrets, feature flags) come from environment variables, not code. Parse and validate configuration into typed objects at startup, not scattered throughout code. Validate all required configuration at application boot. Missing config should crash immediately with a clear message. Provide reasonable defaults for local development while requiring explicit values for sensitive settings.
