Tailwind CSS: @apply with Responsive Modifiers in @layer Directives

This repository demonstrates a bug where Tailwind CSS's @apply directive doesn't correctly apply responsive modifiers when used within @layer directives. The bug specifically impacts styles applied at larger breakpoints.

Bug Description

The core problem is that Tailwind's @apply directive inside an @layer fails to properly handle responsive modifiers such as md:, lg:, etc. While the base styles might be applied, the responsive variations are often ignored.

Reproduction Steps

1. Clone this repository.
2. Install Node.js and npm (or yarn).
3. Run npm install or yarn install to install dependencies (PostCSS and Tailwind).
4. Observe that the styles in bug.css do not apply correctly at the defined breakpoints.
