/* ruled-ink / 01-redacao-em-dia — curso de redação "Redação Em Dia" (até a v1.62.1, "Margem").
   Escrito a partir de references/education/reference-01 e dos limites da família (tokens.css, design-dna.json).
   Medidas, respiro e margens iguais aos da referência (pedido da Lya); cores, fontes, objeto e composição próprios (R32).
   Visual de biblioteca: a textura de pontinhos da referência no destaque, cor só no grifo, no botão em destaque e nas
   anotações; as folhas têm pauta e o texto delas se escreve sozinho (no destaque ao abrir, na redação ao aparecer).
   v1.63.2: destaque centralizado com o marca-texto verde (esquema lima), a palavra que troca e o quadriculado que acende
   (script.js); abas, revelação, sanfona, cabeçalho e menu são comportamentos globais. */
