I'll create a font previewer component using the Comfortaa font. This component will allow users to see how the Comfortaa font looks with different weights and sizes.

Let's create the font previewer component:

This component creates a font previewer for the Comfortaa font with the following features:

1. It imports the Comfortaa font from Google Fonts using Next.js's built-in font optimization.
2. Users can input custom text to preview.
3. There's a slider to adjust the font size from 12px to 72px.
4. It displays the font in five different weights: 300, 400, 500, 600, and 700.
5. The component is responsive and should work well on various screen sizes.

To use this component, you'll need to have the @/components/ui/slider, @/components/ui/input, and @/components/ui/label components from the shadcn/ui library installed in your project.

You can place this component in your page or layout file to display the Comfortaa font previewer. The previewer allows users to see how the font looks with different weights and sizes, and they can input their own text to preview.

I'll modify the component to create a simple, centered, editable text display with the word "jaguar" using the Comfortaa font. I'll ensure it's mobile-friendly, has letter spacing, and turns off autocapitalize.

This updated component does the following:

1. It displays a large, centered, editable text that initially says "jaguar".
2. The text uses the Comfortaa font and is fully editable.
3. It's responsive and works well on mobile devices.
4. Autocapitalization is turned off using the spellCheck={false} prop.
5. Letter spacing is added using the tracking-wide Tailwind class.
6. The component takes up the full height and width of the screen, ensuring the text is always centered.
7. The font size is responsive, increasing on larger screens.
8. Word breaking is enabled to ensure long words don't overflow on small screens.
9. Grammarly and other text editing extensions are disabled to prevent interference.

To use this component:

1. Make sure you have the Comfortaa font imported in your project.
2. Place this component in your desired page or layout file.
3. The text will be centered and editable, starting with "jaguar".
4. Users can click on the text to edit it directly.

This simplified version focuses solely on the large, editable text without any additional controls or adornments, as requested.
