/* Card Vendor — cardvendor.io
   THE PRICE GUIDE: the site set as the monthly card price guide shops lived
   by. Midnight cover stock owns the covers (owner's ink run, 2026-09-03);
   interiors run on newsprint
   with ruled price columns, tabular numerals, checklist rows, folio
   cross-references, and one yellow flash for the thing worth circling.
   Self-contained: fonts served from ./fonts (OFL, see fonts/OFL-LICENSES.txt),
   no CDNs, no build step. A printed object has one light; there is no dark
   variant by design. */
