/* Efeito "glitch" na palavra em destaque do título (inspirado no desregisto de cor
   à Spider-Verse). Fica estático o resto do tempo — só "salta" em rajadas curtas,
   disparadas pelo JS (ver app.js). Usa mix-blend-mode:multiply porque o fundo do
   hero é branco: "screen" (o mais comum em tutoriais de glitch) fica invisível
   sobre branco, "multiply" é o equivalente correcto — como tinta CMYK desalinhada
   em papel. As camadas de cor só aparecem quando .is-glitching está activa.
   Estrutura: .glitch (camadas ciano + rosa) envolve .glitch-inner (o texto real,
   que também distorce/desfoca) que por sua vez tem uma 3ª camada de cor
   (amarelo-esverdeado) e um bloco quase opaco — é este bloco, combinado com o
   desfoque do texto real, que garante que a palavra fica mesmo ilegível por um
   instante no pico, e não só "com cor a mais" à volta. */
