/* ========================================
   IKITAI — Bundles & basket-building

   Styles for the #bundles section, the bundle size modal, and the two
   basket-building elements in the cart drawer (the free-shipping progress bar
   and the "complete the bundle" nudge).

   The visual hierarchy here is doing real work. Three bundle cards sit side by
   side; the last one — the full four-piece set at the deepest discount — is
   the only one with a red border, a flag, and a filled button. The two smaller
   ones exist so the big one has something to be compared against. Everything
   each card claims is arithmetic on the real list prices in PRICE_BOOK; see
   bundlePriceMarkup() in cart.js.
