Add a pdfout package that renders the fetched chapters to a single PDF and an export package holding the whole pipeline, so the CLI and an embedding program share one code path and reject the same inputs. The default page is 90x160mm rather than A4 with large type: a viewer scales a whole page to fit the screen, so on a phone the page shape decides legibility and a wide page just gets shrunk. Embed DejaVu Sans in the binary. Vietnamese needs the Latin Extended Additional block, and a headless host often has no fonts installed at all, so rendering must not depend on finding one. An explicitly named font is never silently substituted. Font data is passed as bytes because fpdf resolves a font path against its own font directory. Keep the original per-chapter text output available behind -txt.
