The three A4 SVG/PDF aids use searchable DejaVu Sans text. DejaVu is third-party and not included in SubjectNest's CC BY 4.0 content grant; see copyright and font license. The vector layout, wording and text alternatives are original SubjectNest work. The generator is under MIT. A fixed source-date value makes repeat PDF renders byte-stable with the same rsvg-convert/font environment. Full text/tactile alternatives remain usable if the renderer changes.
