Original unmodified Bitstream Vera Sans regular and bold full TTF files supply most printable text. Their full copyright/permission/FAQ is in BITSTREAM-VERA-LICENSE.txt. The preserved earlier FONT-NOTICE.md describes that two-font base. This new Year3 native also includes unmodified DejaVu Sans regular for symbols missing from Vera, particularly the right arrow. Full installed upstream-font copyright/permission and clearly separate Debian packaging notice are retained in DEJAVU-FONT-COPYRIGHT.txt. The font itself has the Bitstream permission with DejaVu changes in the public domain; no Debian packaging code is imported. No GPL PDF-font exception or Arev claim is made.
Original full source-font files and each full licence/notice are independently pinned in DEPENDENCIES.json; source font bytes are not renderer-produced subset streams. No glyph design was edited. Native PDFs embed subsets/Unicode maps under applicable font permission, separately from the original educational CC BY4 grant and native software Apache2 grant. Retain all actual complete terms, name restrictions, no standalone font-sale condition and disclaimers. Source SVG/HTML still requests a local renderer font; this PDF conversion substitutes the disclosed font for printable text without a physical calibration claim.
