   styles/landing/ — Página pública de download do DuplaDesk
   ----------------------------------------------------------------------------
   Dividido em styles/landing/NN-*.css, um arquivo por seção. O prefixo
   numerico e a ordem da cascata, a mesma das tags <link> de download.html
   e das páginas de pages/: parte nova entra com o numero da posicao em que
   deve valer, em todas elas.
   ----------------------------------------------------------------------------
   Aplicado o sistema de design v3:
   - tokens do design system (sem bloco próprio `--landing-*`)
   - sem `linear-gradient` no body (vira cor plana do accent)
   - sem `transform: perspective/rotateX/translateY` na hero (decorativo)
   - sem sombras coloridas (sombras neutras sobre rgba(14,17,22,...))
