Personal homepage

The new homepage is index.html, with styles in assets/css/personal.css. It is plain HTML/CSS, with no JavaScript, CDN fonts, or additional build dependencies. GitHub Pages copies it as a static file; the existing Jekyll site and document URLs remain supported.

• Homepage: index.html
• Shared style: assets/css/personal.css
• Publications and CV layout: _layouts/personal.html
• Portrait: images/me.png
• CV: files/CV_JianghaiChen.pdf
• /about/ redirects to / using the existing Jekyll redirect plugin.

Preview the homepage with python3 -m http.server 4173 --bind 127.0.0.1 and open http://127.0.0.1:4173. For all Jekyll-generated routes, use bundle install and bundle exec jekyll serve. The Python server only previews the static homepage, not the Jekyll routes.

Content is based on the existing website and profile README. Education is worded without asserting a current enrollment status. The existing CV is retained; review it before publishing if it needs updating.
