The scan is a bilevel 300 dpi JBIG2 layer plus lower-resolution colour, so storing every plate as 8-bit PNG only added size. tools/optimize_plates.py writes copies under work/plates-opt (bilevel to generic-mode, lossless JBIG2; genuine halftone to JPEG q88) and repoints work/pages at them; plates/ and src/ are untouched. The Dockerfile builds jbig2enc and adds qpdf, ghostscript and img2pdf. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
