/* ====================================================================
   web/css/aprender.css — a página "Aprender o método" (rodada
   Ecossistema, 07/10/2026). Quem monta é js/aprender.js.

   Escopo: toda regra começa por `#module-aprender` (ou `.apr-…` dentro
   dele). Sempre o design system novo (direção A, selo Apple/ChatGPT),
   sem depender de flag: os tokens abaixo copiam os de visual-a.css
   (`--va-*`) e o padrão do cockpit (hairline, raios 12–16, uma só cor
   de ação; dourado só como acento).

   Layout: ≥ 900 px lista à esquerda + lição à direita (coluna de
   leitura ~680 px). 769–899 px: lista como entrada, lição no lugar dela.
   ≤ 768 px: lista como entrada, lição por cima da tela inteira.
   Refino 08/10/2026: medido contra o padrão visual (cabeçalho de
   web/css/barra.css) — cards 16, opções 12, rótulos em caixa normal.
