/* 2) Hero STATYCZNY na .hero-cine — Ken Burns CAŁKIEM WYŁĄCZONY 26.06 (3. zgłoszenie Szymona).
   GENEZA: animowanie scale na <img> hero z teksturami (cegły/framugi) re-samplinguje obraz
   klatka po klatce → na części ekranów drobne drganie/shimmer = „heroshot się trzęsie".
   translateY usunięto wcześniej, scale-only + will-change/GPU NIE wystarczyły do GWARANCJI gładkości.
   Krzysztof zażądał pewności („make sure, że błąd się nie pojawi") > efekt. Zero animacji = 0% drgania.
   Delikatny zoom zostaje TYLKO w pełnoekranowych hero gastro/studio (hg-bg/hs-bg — tło, inny
   mechanizm, chwalone, nigdy nie zgłaszane). NIE wracać do KB na .hero-cine bez realnego testu
   na sprzęcie klienta — to ryzyko regresji „trzęsienia”. */
/* BEZPIECZNY "wow" na hero = jednorazowy FADE-IN (opacity), nie zoom.
