/* REGRA DURA (mobile): NENHUM campo pode dar zoom no iOS ao ser focado.
   O Safari iOS amplia a tela sempre que um campo focado tem font-size < 16px —
   e ignora user-scalable/maximum-scale no viewport; só o tamanho da fonte resolve.
   A regra acima não basta: .form-input/.form-select/etc. sobrescrevem com um
   tamanho menor e o zoom "escapava" tela por tela. Aqui fecha de vez, com
   especificidade acima dos componentes e só em telas touch (tablet em paisagem
   incluso, que a regra por largura acima não pegava). Desktop segue menor. */
