/* Brightway Academy — site institucional
   Linguagem visual "acadêmica" do documento de marca: bordô institucional, creme,
   serifada, réguas finas, versalete espaçado. NÃO é uma landing: sem CTA laranja,
   sem contagem regressiva, sem gradiente de conversão. O trabalho desta página é
   responder à busca "Brightway Academy" com algo que pareça uma editora de verdade,
   porque é o que ela é. */

/* Fontes da marca servidas do próprio domínio, em vez de fonts.googleapis.com.

   Work Sans é variable: um arquivo cobre 400–700, no lugar dos quatro que o Google
   mandava. Libre Baskerville não tem versão variable, então continuam três arquivos —
   regular, bold e o itálico dos <em>. O `unicode-range` é o mesmo subset latin que o
   Google servia. */
