The five original A4 SVG/PDF organisers use DejaVu Sans. PDF rendering may embed font subsets. The font's separate DejaVu licence, derived from the Bitstream Vera licence with DejaVu additions, is not replaced by SubjectNest's licence. The SVG teaching words remain editable and the full text/tactile routes preserve the content without relying on colour or layout. Generator code is Apache-2.0; original teaching output is CC BY 4.0.
