/* A ALTURA FICA NA IMAGEM, não no container — e em px, não em %.
   Duas tentativas falharam antes:
   1) `max-height:100%` → quem limitava era a largura; a imagem mais larga
      (manômetros) estourava 24px por baixo e era cortada pela legenda;
   2) `height:100%` dentro de um grid de linha `auto` → porcentagem cíclica:
      sem altura definida para resolver contra, o navegador cai em `auto` e
      volta à altura natural (o bug reaparecia).
   Com altura definida em px + object-fit, o navegador encaixa e centraliza
   sozinho. A altura do bloco vira 196 + 44 de padding = 240px. */
