   Anchored on the one fact we can verify from the live site:
   the brand graphite #252525 (msapplication-TileColor) over a
   white canvas (theme-color #ffffff). Everything else is a
   disciplined neutral ramp plus a single warm promo accent.

   ASSUMED / TO CONFIRM: the promo accent (--mk-red) and the eco
   green (--mk-green). The site is discount-led ("Скидка 54%",
   "Старая цена"), so a warm signal red for promos/old-price is
   the most probable accent — but it was inferred, not sampled.
   Swap these two values once the real brand palette is shared. */
