/* ══════════════════════════════════════════════════════════════════════════════
   PDF MARKUP (/tools/sign-pdfs/): the Hub tool (PDF brief Appendix C) re-skinned with the site tokens per §4.3.
   Items use the same font files the PDF gets, with kerning and ligatures off because pdf-lib applies neither:
   what is on screen is what is written. The @font-face URLs below are the same URLs app.js fetches
   (new URL('./fonts/…', import.meta.url) from /tools/sign-pdfs/app.js); build.py prefixes them for the /1 /2 previews.
   UNCHANGED from the Hub, on purpose: @font-face, .pdfm-font-*, .pdfm-ink-*, the .pdfm-item geometry and font
   rules, the white page. Colour pairs are measured in designs/d1/palette.py (tools/contrast.py). Fallbacks keep it
   working under Design 2, which lacks --tile, --teal-a and --r-lg.
