/* 送礼物 R26 (kanban#9993433): the composer sheet shared by the product page and the
   cart page -- markup's twin moved verbatim out of mall-product.html (R21,
   kanban#9993392). Frozen glass tokens: rgba(255,255,255,.72) + blur(20px)
   saturate(1.5), top radius 28px, cinnabar CTA #B5432E->#8F3222, champagne hairlines,
   Songti for the seal chars. The .stepper rules are scoped to the sheet: on the mall
   home the bare .stepper class belongs to the cart quantity control. */
