What are the sequential steps to create a design system, and what is the responsibility scope of the front-end developer?

[OhanyanSofia]

I'm trying to understand how to approach building a design system in a structured way. I want to know:

• What are the key steps or phases involved in creating a complete design system?
• What parts are typically handled by front-end developers, and what is usually out of their scope?
• Are there best practices or tools commonly used by developers when implementing a design system?

I'd appreciate any insights or real-world experience on this topic.
