Sharing another small CSS tweak I’ve been experimenting with ✨  
With this trick you can freely set different app widths on desktop or define a default width when the app first loads.

```auto
#page-root:has(.unique-screen-size) {
  max-width: ...px; /* set your preferred width */
  margin: 0 auto;
}

```

Wonderful! Does the size remain fixed when you change your browser size?

Yes — since it’s set in pixels, the custom CSS keeps the width fixed even if you resize the browser.
