The eight A4 PDFs use embedded searchable subsets of DejaVu Sans. Original circle/square/dash/round-divider illustrations are drawn from simple authored geometry; no external illustration or music notation font is imported. Exact linear text and raised/no-sound equivalents preserve all choices including undecided cells.
The installed font's verbatim rights are in dejavu-font-copyright.txt, copied from the system package notice. DejaVu changes are public domain; original Bitstream Vera rights and restrictions remain as stated. This notice is not replaced by the original teaching resource's CC BY 4.0 licence. The pack includes no original font file or renamed font. PDF font subsets remain subject to those terms. Searchability/embedding is computer-checked, not a universal accessibility certification.
