/* anotacoes.css — a margem de comentários do Caderno (anotacoes-ui.js).
 *
 * Variante «B» aprovada pelo autor em 2026-10-06. Arquivo à parte pelo mesmo motivo do
 * avaliacao.css: o style.css é ponto de encontro de várias sessões. Só tokens do tema
 * (DESIGN-SPEC §3), nenhuma cor nova. As três camadas se distinguem por rótulo escrito
 * e pelo traço — tracejado (só eu), cheio (coautoria), duplo (pares) — na borda do
 * cartão e no sublinhado do grifo; nunca só pela cor. Cantos retos, alvos de 44px. */
