/* ======================================================================
   ФЛЕКС, virtual cards landing
   Style: "Dylanbrouwer, Brutalist type foundry at dusk"
   Mixed theme with a dark-to-light rhythm: dark monument hero (#161616)
   dropping into light content (#f8f8f8 canvas, #ffffff cards), closing
   on a dark CTA + footer band.
   One chromatic accent only: ember #ff6436, small functional elements.
   Display: Anton (monument only). Body: Inter 500. Meta: IBM Plex Mono.
   Radius split: cards/inputs 0px, panels 14.4px, interactive pills 9999px.
   No shadows, no elevation: flat surfaces + hairline borders only.
