/* ============================================================
   Nitee Publications — Design tokens (v2: "Catalog & Stamp")
   No blue anywhere. A warm ink-black replaces navy as the dark
   base, and a bold marigold/mustard becomes the dominant accent
   — used the way foil-stamping or a rubber ink-stamp would be
   used on real book jackets and library cards. Burgundy and olive
   sit underneath as secondary, non-blue accents for variety.
   Display type is a high-contrast serif (Fraunces); body is a
   clean sans (Inter); a mono face (IBM Plex Mono) carries all the
   "catalog data" — ISBNs, prices, dates, stamp text — echoing how
   those details are actually typeset on a card catalog or colophon.
