/* =============================================================
   PÁGINA FEED — uma tela (100svh) só com o mural "Drift Wall"
   (React Bits, MIT, reactbits.dev), em JS puro: colunas de quadros que
   derivam em perspectiva, com imagens de todos os cases do site. O quadro
   sob o mouse vem para a frente e leva ao case. Cores pelos tokens de
   nav.css (o fundo e a névoa das bordas seguem o tema).
