   NAVBAR DROPDOWNS — tema dark (Mercados / Simuladores)
   O menu é estilizado por JS inline (menu.style.cssText → background:#fff,
   link color:#111827) e o hover cai numa regra global !important
   (site-modern.css: `header nav a:hover { color:#35d0ff !important }`)
   sobre fundo quase-branco → texto fantasma. Nas páginas com tema Terminal
   Pro precisamos de fundo escuro + texto claro + hover teal legível.
   Só `!important` vence os estilos inline do JS; a especificidade extra
   (.main-nav .nav-dropdown-menu, 3 classes) + carregar por último vencem a
   regra !important global de hover.
