   :root block so the ordering flow reads as the same product as the marketing site. Mobile-first:
   most orders come from a phone, so the base rules target a phone screen and desktop is the
   exception (see the single max-width query near the bottom), not the other way round. */

/* The whole flow shows and hides things with the `hidden` attribute, which works only through the
   UA rule `[hidden]{display:none}` -- and ANY author rule that sets `display` on the same element
   outranks it. Every button here is `.btn*{display:inline-flex}` and several rows are
   `display:flex`, so without this those elements ignore `hidden` completely and render anyway.
   That is not cosmetic: it is what put "Да, отменить" on screen next to "Отменить заказ" with no
   intervening click, turning the deliberate two-click guard on a destructive action into one tap.
   !important is the point of the rule -- it has to beat the class rules by design, not by order. */
