-  The default border color has changed to `currentColor` in Tailwind CSS v4,
-  so we've added these compatibility styles to make sure everything still
-  looks the same as it did with Tailwind CSS v3.
-
-  If we ever want to remove these styles, we need to add an explicit border
-  color utility to any element that depends on these defaults.
