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
