Four original A4 diagrams are generated from local source into SVG/PDF pairs. Each SVG contains a descriptive <title> and <desc> and full-word visible labels. Each PDF is one-page A4 with selectable text and embedded DejaVu Sans, but is untagged. Use the complete text alternatives for reliable nonvisual reading order and tactile reconstruction. A rendered paper inspection checks only clipping/legibility; it is not a specialist accessibility user test.
DejaVu Sans remains under its separate upstream licence, reproduced in dejavu-font-copyright.txt. SubjectNest's CC BY 4.0 covers our layout and teaching copy, not QCAA, agency source pages or the font. No externally owned map, photograph, satellite image, warning, logo or map tile is embedded.
