Pro-government narrative

Closing the Seine due to water quality concerns is a necessary precaution and shows responsible public health management. Recent wet weather has increased runoff and pollution, making swimming unsafe. Protecting public health must come first. Authorities are simply ensuring future events proceed safely once conditions improve and the river meets health standards.
