Quarto PDF: отрегулируйте поля подписей в SUB-цифрах рисунков

После обширных поисков и погони за кроличьими норами я нашел это как одно из решений. Вместо

::: {#fig-TheFigure layout-ncol = "2"}

использовать

::: {#fig-TheFigure layout = "[10,-1,10]"}

Отрицательное число указывает на пробел между фигурами. Хм.

Если есть другое решение, мне интересно узнать о нем.

Вы можете использовать команду \captionsetup вместо subfigure для управления субтитрами. Вы можете использовать \captionsetup[subfigure]{margin=15pt} или \captionsetup[subfigure]{width=0.8\textwidth}, чтобы настроить поля между субтитрами.

**This is the main document text. @fig-TheFigure shows two subfigures with long captions, and an overall captions beneath them. *I want the subfigure captions to be separated, not bumping into each other as they are here.* As one attempt, before the figure I inserted inline \LaTeX\ code: `\captionsetup{width=0.9\textwidth}`. Notice that the main caption has the reduced width, but not the subfigure captions.** Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
