Exports (blue: this module) use the server's Chromium to draw the studio's own /render page, then turn that page into files.

The deck is only useful once it leaves the studio. LinkedIn takes a carousel as a PDF document; a newsletter wants images; a colleague wants one file that opens anywhere. This module is the last step: the export menu in the editor, one API route, and the code that turns a rendered deck into four kinds of file.
