/* Minimal bidfax-flavoured single-lot page. Light theme, dense grid of
   information, prominent price card, gallery-forward hero. Deliberately
   no framework - one stylesheet, vanilla HTML, ~250 lines.

   Colour palette: stay neutral. Black text on near-white card backgrounds,
   subtle grey borders, single red accent for the final price (the thing
   a buyer's eye is drawn to on any auction listing). */
