/* ALINHAMENTO DOS CAMPOS DA GRADE.
 *
 * O label era `display: block`, então o campo começava onde o texto acabasse:
 * "Garantia temporal pretendida" ocupa duas linhas, "Anos mínimos de série"
 * ocupa uma, e os dois campos da mesma linha saíam em alturas diferentes.
 *
 * Coluna flexível com o campo empurrado para o fim resolve sem depender de o
 * rótulo caber numa linha — que é uma condição que nenhum texto em português
 * respeita por muito tempo. O `:not(.checkbox)` preserva a caixa de marcação,
 * que é deitada de propósito. */
