Describe the bug

Hi, I just discovered a tiny bug.

When you copy the CSS text for Tailwind CSS and have Themes selected, there is a trailing comma where it shouldn't be.

@layer base {
  :root {
    --text: #050315;
    --background: #fbfbfe;
    --primary: #2f27ce;
    --secondary: #dedcff;
    --accent: #433bff;
  }
  .dark {
    --text: #ebe9fc;
    --background: #010104;
    --primary: #3a31d8;
    --secondary: #020024;
    --accent: #0600c2;
  }
}, <----- RIGHT HERE

Should be:

```css
@layer base {
  :root {
    --text: #050315;
    --background: #fbfbfe;
    --primary: #2f27ce;
    --secondary: #dedcff;
    --accent: #433bff;
  }
  .dark {
    --text: #ebe9fc;
    --background: #010104;
    --primary: #3a31d8;
    --secondary: #020024;
    --accent: #0600c2;
  }
}

Also love your site! Well done and super useful.
