The original vector drawings request DejaVu Sans for readable letters and numerals. A local rendering of the PDFs may embed a subset of that font. The DejaVu font is separate from SubjectNest's CC BY 4.0 aid artwork. The source package's copyright and applicable Bitstream Vera licence notice are preserved in dejavu-font-copyright.txt; see the DejaVu project for upstream information. The generator does not redistribute a standalone font file. If a future build substitutes a font, check that font's embedding and distribution terms before release.
