/* Every element-level rule in this file ends in :where(:not(.vs-embed *)).
   The backend's checkout and account components render in the light DOM
   (Stripe's iframes need it) inside .vs-embed on /checkout/, /account/ and
   /order-confirmed/, and a bare button{} or input{} here would restyle them
   — input[type=text] at (0,1,1) beats their .vs-input at (0,1,0). :where()
   adds no specificity, so every rule ranks exactly as it did before. */
