The provided article content appears to contain only technical CSS code and markup rather than the actual news article text about American Carrie Mancuso opening an art studio in Gaillac. The readable article content needed for translation and rewriting is not present in the submitted material.

To properly complete this task, the actual French news article text would be required, containing information about Carrie Mancuso, her background, the art studio opening, location details in Gaillac, and other relevant details that would typically be found in such a cultural news story.

Without access to the original article content, it is not possible to provide a complete and detailed rewrite in American English as requested.
