   MidasBot — branco premium, acabamento big tech, minimalista.

   Paleta: o logo é laranja-fogo (#F03D06). O dourado entra como a
   outra ponta do mesmo metal, nunca como cor de texto corrido —
   sobre branco o ouro tem contraste baixo demais para texto pequeno.
   Regra: ouro/fogo em display, filete e ícone; ink em tudo que se lê.
