   MASTER FLAG WINDBANNER — style.css
   Palette extraída da logo: dourado + vinho (bordô), as duas cores

   ecoa o brasão/selo da marca) + Inter (corpo, legibilidade).
   Linguagem visual: cantos assimétricos, botões chanfrados e
   bandeirolas (bunting) no divisor de seção — motivo literal ao
   produto (windbanners são bandeiras).
