mongkonsrisin/mongkonsrisin-dot-com — reverse-engineered prompt

Build me a calm personal website for mongkonsrisin.com using simple HTML, CSS, and a little JavaScript. I want it to feel soothing, clean, and personal, with soft Catppuccin inspired colors instead of anything harsh or flashy.

Make it work well as a small homepage, something that introduces me, gives the site a polished landing page feel, and can be easily edited later. Keep the design minimal, cozy, and responsive on phones and desktops. Use nice spacing, readable text, subtle visual details, and a simple structure that feels intentional.

Please keep it lightweight with no complicated framework. Put everything together so it can run as a static site from an index.html file with assets as needed. If there are existing files, improve them rather than overcomplicating the project. Make sure the final result looks finished, not like a blank template.
