Fix Email Web App Styling

I need help to fix the styles of an email web app. I have a Figma design and the initial implementation, but it's functional without the correct styling.

The app is built using Typescript, with Radix and Tailwind. I copied the code from Figma, but the Tailwind styles are not applied, resulting in:

- Layout problems
- Color inconsistencies
- Typography issues

I have played with tailwind v4 and v3 and couldn't resolve it. This project is only to solve the issue with styling. I'm not looking for any additional visual improvements.

Ideal skills and experience:
- Proficient in Tailwind CSS
- Experience with Radix
- Strong eye for design to accurately implement Figma designs
- Troubleshooting CSS and layout issues

I will provide link to my Figma design.
