How does struct{} take zero bytes in Go

https://www.bud1m.com/blog/go-empty-struct/
Hello gophers!

While learning Go, I came across struct{} and started wondering how its zero-size behavior actually works under the hood. I couldn’t find a detailed explanation that covered the internals, so I decided to investigate and write a blog post sharing what I learned.

Feel free to share any questions, feedback, or additional insights.
