// CAUTION: Lightning CSS minifies the CSS, and it refuses a pseudo-class that
// comes after a pseudo-element. Do not use a Tailwind class that puts the two
// in that order, such as `file:disabled:opacity-50`, because Lightning CSS
// stops the build on the `::file-selector-button:disabled` selector that the
// class produces. See https://github.com/parcel-bundler/lightningcss/issues/1292
// The Skeleton 2 Tailwind plugin made that selector on its own, and Skeleton 5
// does not, so the project no longer needs a different minifier.
