   LOGO NO NAVBAR — COMO FUNCIONA:
   A logo (logo-transparente-02.png) é a versão colorida horizontal.
   - Sobre o hero (navbar transparente): CSS aplica filter para branca
   - Após scroll (navbar--solid): filter é removido → cor original
   - Nunca haverá fundo preto → filter é apenas brilho + inversão.

   SOLUÇÃO DEFINITIVA DA LOGO:
   • Estado inicial (sobre hero): fundo transparente.
     A logo usa filter: brightness(0) invert(1) → fica branca.
     Isso funciona com QUALQUER arquivo de logo colorida.
   • Após scroll (classe .navbar--solid): fundo branco real.
     filter é resetado para none → logo aparece na cor original.
   • NUNCA há fundo preto — o background é sempre branco ou transparente.
