 * um destes dois valores; não introduza um terceiro número ad hoc.
 *
 *   768px — "mobile/compacto": tipografia, grids, modais,
 *           página de login/registro.
 *   900px — "split do editor": ponto em que .editor-split empilha
 *           editor/preview/IA. Não alterar este valor sem
 *           coordenar com o breakpoint de 640px da toolbar
 *           (colapso dos botões secundários), que opera perto
