/* Bloco de código da documentação cresce com o conteúdo.
   A regra GLOBAL do base.css (`pre { height: 50vh; min-height: 150px; resize: vertical }`)
   existe para os VIEWERS — console de log, telemetria, tabelas roláveis —, onde altura fixa é
   o comportamento certo. Ela alcançava também o markdown desta tela, e ali é defeito: um
   trecho de 3 linhas ocupava 525px (50vh) de caixa quase vazia, com alça de redimensionar,
   e cada página virava maratona de rolagem. Medido em 19/08/2026: TODOS os `pre` da página
   3.3 mediam 525px, de 2 a 4 linhas de conteúdo.
   O teto de 70vh fica para o trecho realmente longo continuar rolando dentro da própria caixa. */
