   0. TIPOGRAFIA
   Inter, hospedada aqui mesmo em assets/fonts/ — nao vem do Google Fonts.
   Servir do proprio dominio e mais rapido (nao abre conexao com terceiro),
   nao expoe o IP do visitante a outra empresa e mantem a promessa de que a
   pagina nao faz nenhuma requisicao externa.

   E uma fonte VARIAVEL: um arquivo so cobre os pesos de 100 a 900, entao os
   pesos intermediarios usados aqui (550 nos links do menu, 650 nos titulos
   de lista) sao renderizados de verdade, e nao arredondados.

   O unicode-range faz o navegador baixar o arquivo latin-ext apenas se algum
   caractere fora do latim basico aparecer na pagina — hoje, nenhum. Na
   pratica so os 47 KB do latin sao baixados; o portugues cabe inteiro nele.

   Licenca SIL OFL 1.1 — o texto exigido esta em assets/fonts/OFL.txt.
