/* ===========================================================================
   Athanor — antiquarian catalogue styling.

   Self-contained on purpose: one self-hosted display face (Cormorant, SIL OFL
   1.1; no third-party font CDN) over a system-serif body/fallback, plus one
   small progressive-enhancement filter script and eBay-CDN-hotlinked covers.
   The "signature" element is the catalogue card (the listing treatment): a
   tipped-in cover plate, a monospace accession number, and a wax-seal "just
   listed" mark. Everything else stays disciplined.

   Quality floor: responsive grid, visible :focus-visible states, motion gated
   behind prefers-reduced-motion, no layout shift (aspect-ratio on plates).
   =========================================================================== */
