Is it impossible to ship designs 100% accurate?

Designer here, no coding experience.

1. I created a design in Figma, using Shadcn UI components.

2. I uploaded the file to v0, used Claude to create a proper prompt and the whole thing got built.

3. I exported the code to Cursor.

4. Installed Shadcn and all other libraries.

5. After looking like dogsh*t, I tried to export a component from Figma as Code (with a Plugin), and still, does not even look close to the design.

How can you ship designs from Figma and turn them into web apps?

Has anyone successfully done that yet?
