Why France chose Jean Bart over a Clemenceau rebuild

Why did the proposed Clemenceau rebuild or carrier conversion fail to proceed?

Postwar budget priorities favoured completing Jean Bart, while carrier flexibility had yet to make battleships instantly obsolete.

Money drove the postwar choice: France preferred completing Jean Bart to completing Clemenceau as a carrier conversion. Battleships still had value as frontline units, even after carriers proved their reach. A carrier could also change its air group far more easily than a battleship could replace its main armament. France was choosing between attainable capabilities within a tight budget rather than declaring one capital-ship type instantly obsolete.
