   TRACE · Design System
   Base visual: preto + luz azul, glassmorphism e tipografia Drupadi.
   Reutilizavel por todas as LPs do estudio.

   Regra de performance deste arquivo:
   nada de filter: blur() em camada grande, nada de mix-blend-mode em secao
   inteira, nada de will-change espalhado e nada de animacao infinita que
   mexa em layout. Suavidade vem de gradiente, nao de filtro.
