/* Cabeçalho público, o mesmo na landing e no blog (shared/views/site-header.ejs). O visual base serve às
   páginas legais, no tema do aplicativo; .site-header--marketing é o da landing, que o blog também usa.
   Medida em rem só sai de token (ou de múltiplos de --space-4, quando não há token): o blog roda na raiz de
   16px e refaz esses tokens sobre a raiz compacta da landing (blog.css) para o cabeçalho sair do mesmo tamanho.
   Vem depois das folhas da página, para ganhar dos estilos de link de cada site no empate de especificidade. */
