/**
 * Header, menu principal e menu mobile - Bem Estar Veiga
 *
 * Fonte única do layout do cabeçalho. Substitui os ajustes espalhados em
 * no-overflow.css, logo-size-fix.css e logo-responsive-fix.css, que se
 * contradiziam com !important e escondiam itens do menu.
 *
 * Mobile first: até 1199px o cabeçalho usa o botão de menu (hambúrguer) com
 * as 9 seções e o submenu de assistências em acordeão. A navegação horizontal
 * só aparece a partir de 1200px, largura em que os 9 itens realmente cabem
 * sem invadir a logo. O espaçamento entre logo, menu e botões é fluido
 * (clamp), então o cabeçalho se ajusta em vez de quebrar.
