  class="cm">// This issue can only occur if somebody does the following things:
  class="cm">//
  class="cm">// 1. Uses a shorter at-rule than `@page`
  class="cm">// 2. Disables Lightning CSS from `@tailwindcss/postcss` (because Lightning
  class="cm">//    CSS doesn't handle custom at-rules properly right now)
  class="cm">// 3. Sandwiches the `@tailwindcss/postcss` plugin between two other plugins
  class="cm">//    that can handle the shorter at-rule
  class="cm">//
  class="cm">// Let's use the more common case as the default and we can adjust this
  class="cm">// behavior if necessary.
