[Site] Fix Cloudflare wrongly minify CSS 4

Cloudflare seems to bug because of the `@layer` instructions and generate a "little too much compressed" CSS code 😆

```css
  .LiveMemory-Main {
    border:1pxsolidvar(--color-border);
    width:100%;
    aspect-ratio:1.6auto;
  }
 ```

 By suffixing the file ".min.css" it should not over-compress it.
