The cover is a full-bleed mosaic of historical Bengali types filling the word
ব্যঞ্জণ, produced by tools/gen_cover_mosaic.py from plates/ and fonts/ alone
(build.sh remakes it if missing). It is static, so ebook readers can cache it.
The mark on the About this edition page is drawn by tools/gen_seal.py, seeded
from a SHA-256 of src/ (never the build's own outputs), so it changes exactly
when the transcription does. The colophon is shortened to name the cover
typefaces and the mark's mechanism, and drops the trailing ProQuest note.
