The original SVGs request DejaVu Sans for legible labels. The PDFs may embed font subsets from the local rendering environment. DejaVu is separately licensed from SubjectNest's original CC BY 4.0 artwork. The relevant package copyright and Bitstream Vera font licence are preserved in dejavu-font-copyright.txt; upstream project information is at DejaVu Fonts. No standalone font file is redistributed. A different rendering font must be checked before use.
