/* The fine-wine sticky backing card.
   One card follows the reader. One field, $0 to the packet wage.
   Desktop: right rail. Mobile: bottom bar.
   Built ENTIRELY on the house tokens (2026-08-12): the old file carried its
   own silver/platinum-blue palette, which made this the one component still
   off the gold-green-black register after the sitewide pass. Tokens theme
   themselves, so this file no longer needs a dark block at all — both hosts
   (work.html, explore.html) load a token sheet before it.
   Copy law: em dashes never reach the screen. */
