feichai0017/personal-website ? reverse-engineered prompt

Build me a modern personal website that feels clean, calm, and professional, with a soft Morandi color palette.

I want a single page site with sections for Home, About, Projects, Experience, Tech Stack, and Contact. It should be fully responsive so it looks great on desktop, tablet, and mobile, and it should include a dark and light mode toggle. Add smooth animated transitions and subtle motion so the page feels polished without being distracting.

Please make it easy for me to customize the text, links, projects, and timeline entries later. The contact area should look like a real contact form and the whole site should have a minimal, elegant style. Use modern web best practices, and if you need to check anything current, look up the latest docs online.
