The five original A4 SVG/PDF layouts use DejaVu Sans. PDF rendering may embed a font subset. DejaVu fonts have their own licence, derived from the Bitstream Vera licence with DejaVu additions; that font is not relicensed as SubjectNest artwork. The SVG text remains editable and the full text/tactile routes provide the teaching content without the font or image layout. Generator code carries Apache-2.0; the original teaching layouts carry CC BY 4.0.
