   M-POWER — arkusz strony (one page)
   ---------------------------------------------------------------------------
   Jeden zestaw tokenów dla wszystkich sekcji: kolory, typografia, odstępy,
   promień (2px — techniczny, prawie prosty kąt) i ruch. Sekcje nie definiują
   własnych rozmiarów nagłówków ani przycisków — korzystają z klas wspólnych.

   Kontrast (policzony): #009dff na jasnym tle = 2,7:1, więc jako kolor TEKSTU
   używamy --blue-ink (#0071b8, 4,8:1), a na ciemnym --blue-soft (#66c4ff).
   Sam #009dff zostaje na drobne akcenty graficzne (kreski, znaczniki).
