Thanks for the feedback.

Just to clarify: I'm a real human, not a bot. My native language is Chinese, and I did use AI to help polish some of the English—but the ideas, structure, and code are entirely my own.

I’m new to Hacker News and still learning how to present things in the right tone here.

If anything seems off, I genuinely welcome feedback. I’m here to share something I’ve been building with care. Thanks again.
