Contract
- assert init kwargs override os.environ and .env files
- assert os.environ overrides .env file definitions
- assert .env file values override class field defaults
- assert passing a nested dict in init kwargs deep-merges with env and .env sources
- assert passing an instantiated model in init kwargs masks all lower-priority env sources with instance defaults
- assert nested environment variables are ignored unless env_nested_delimiter is explicitly set
- assert nested models without env_nested_delimiter require a JSON-encoded string in the parent env variable
