/* =============================================================
   Art & Print Specs — the print-production reference page (/art-info).

   Same rule as apply.css and seller-info.css: built entirely on home.css's
   tokens (--acc, --grn, --blu, --red, --bg, --panel, --line, --tx, --head,
   --body, --mark), no new colors or fonts. Mirrors seller-info.css's
   structural vocabulary (hairline-bordered card grids, .ai-table, the FAQ
   accordion) under its own "ai-" prefix rather than sharing a stylesheet,
   so each pitch page stays self-contained.
