/* ============================================================
   TRIVIX — design system "Prisma 120"
   Lei da marca: tudo deriva de 120° (rotações, mitras, espectro
   em três luzes) + paradas secas de maquinário (ease CNC).
   Governança de cor: superfícies planas monocromáticas; o
   espectro UV→ultramarino→menta só aparece em EVENTOS
   (bordas, varreduras, hovers, CTAs).
