  ╰─▶ Because liblaf-grapes>=9.0.0 depends on cachetools>=6,<7 and only the
      following versions of liblaf-grapes are available:
          liblaf-grapes<=9.0.0
          liblaf-grapes==9.0.1
          liblaf-grapes==9.0.2
          liblaf-grapes==9.1.0
      we can conclude that liblaf-grapes>=9.0.0 depends on cachetools>=6,<7.
      And because your project depends on cachetools>=7 and liblaf-grapes>=9,
      we can conclude that your project's requirements are unsatisfiable.
