The original SVGs request DejaVu Sans, with generic sans-serif fallback. rsvg-convert embeds/subsets installed DejaVu in the PDFs. The complete installed font notice is retained in dejavu-font-copyright.txt; font rights are separate from the CC BY 4.0 SubjectNest text/diagram licence. PDFs have selectable text but are untagged, so use the complete text and tactile alternatives for a dependable reading order. Rendering and PDF text extraction must be checked after regeneration.
