Initial commit: Ross 1988 re-typeset edition

A searchable, re-typeset edition of Fiona Ross, "The Evolution of the
Printed Bengali Character from 1778 to 1978" (Ph.D., SOAS, 1988),
transcribed from the 431-leaf ProQuest scan. All 431 pages done; 178
plates and 410 inline type specimens cut from the scan; 51 errata.

Tracked: the transcription (src/pages), the preamble and its typographic
decisions, the cut images (plates/ — not reliably regenerable, the crop
specs for the inline cuts were never scripted), tools, and the four
working documents.

Not tracked: the built PDF, which `make` remakes from src/ and plates/;
the ProQuest scan under source/, which is third-party and needed only by
`make prep` and `make plate`; scans/ and work/, both regenerable.
