   2. EFEKT MIRROR — kluczowy element designu

   Strategia: cały <main> dostaje scaleX(-1) jako jeden blok.
   To daje "prawdziwe" odbicie lustrzane — teksty wyrównane do
   lewej w HTML lądują wizualnie po prawej, karty układają się
   od prawej do lewej, kompozycja faktycznie wygląda jak
   patrzenie na stronę przez lustro.

   Header i footer NIE są flipowane; wewnątrz nich klasa
   .mirror nadal lokalnie odbija pojedyncze elementy
   (np. menu, brand__tag, hasła w stopce).
