/* ============================================================
   DUARTE DIGITAL - ANIMAÇÕES E MOVIMENTO
   Keyframes, classes reutilizáveis e efeitos por secção.

   Regras gerais:
   - O estado inicial escondido (opacity 0) só existe com html.dd-anim,
     classe adicionada no <head> quando há JS e o utilizador não pediu
     movimento reduzido. Sem JS, todo o conteúdo fica visível.
   - As entradas animam as propriedades individuais `translate` e `scale`;
     os hovers usam `transform`. Assim as duas coisas não se anulam.
   - prefers-reduced-motion é tratado em responsive.css (desliga tudo)
     e em animations.js (sem parallax, ripple, contadores).
