   Resale trade card (.rtc) — the asset-detail purchase card in RESALE mode.

   Quick-Trade look: a Buy/Sell toggle, the best available price, a share
   stepper and a receipt-style total — wired to the
   simple resale market (fixed-price listings, cheapest-first):
     • Buy  — takes the lowest-priced open offers and shows the buyer fee before
              the real trade settles server-side.
     • Sell — lists the viewer's own free shares inside the ±band of the asset's
              independent valuation; the seller pays the 5% fee on sale.

   Shares the brand language of the primary-market .ad-invest card (white 24px
   surface, electric-blue figures, mint accents) so the two cards feel like one
   family. Lives next to asset.css; loaded by asset.html and styleguide.html.
