Rebuild the four resource PDFs with python tools/resource-pdfs/build.py from the repository root. Requires ReportLab and PyMuPDF (pip install reportlab pymupdf). The content.json file preserves the extracted original resource content; the builder applies the DIN Round reference styling using the repository font files. Existing download paths remain unchanged.

Follow the Learning Loop PDF style guide for fonts, exact color values, page geometry, layout patterns, and export review. New PDF generators should follow the same guide.

The builder also regenerates the four website PNG previews from the first page of each PDF at 1.5× resolution. Always commit these previews with the corresponding PDF changes.
