sandbox_export
Write the book on screen to a file: pdf (the chapter on screen or the whole book, print-ready), epub (reflowable, or fixed to the printed pages), postext (the whole project in one archive, to open again or hand to the postext command line), docx (Word, with a saved Word template when one is named), markdown (the chapter's source) or config (the design settings as JSON). A postext archive can also be written of a book that is not on screen (book): a project as it was last saved, or a sample as it ships, in one of its languages. The file is downloaded by the reader's browser, or — pdf and epub — handed back base64-encoded with deliver: "data". Exporting a pdf or an epub shows that viewer tab.
