/* =====================================================================
   Product cards — vaulted product cards with a spec table and LIVE buy/sell.
   Responsive grid of cards (stack on mobile). Each card: name + ticker chip,
   a vault/insurer detail list, a spec table (Allocation / Buy / Sell /
   Storage / Premium) and a "Buy Now" CTA. Buy/Sell figures are filled live by
   prices.js. Table look modelled on price-grids; BEM, section-scoped.
   Content locked to the 1240 area via .container. Tokens only.
