This page does not include Tailwind itself. It only verifies whether Tailwind is already being loaded by the site.
If Tailwind is active, the box on the right should look styled (blue background, white text, padding, rounded corners). If not, it will look mostly plain.
Notes:
- window.tailwind exists mostly when Tailwind is loaded via CDN script.
- The computed-style check works even if Tailwind is compiled into a CSS file.
