Rebooting this site

This site sat untouched for a while — default Jekyll boilerplate, a lone “Um.” post, and a GitHub Pages build pinned to Jekyll 3.9.3 via the legacy github-pages gem. Time for a refresh.

What changed:

• Moved the build off the legacy GitHub Pages pipeline and onto a GitHub Actions workflow, so the site now builds on current Jekyll (4.x) instead of whatever version the github-pages gem happens to bundle.
• Dropped the github-pages gem entirely in favor of explicit dependencies (jekyll, jekyll-remote-theme, jekyll-feed, jekyll-seo-tag).
• Wired up the monophase theme properly — navigation and social links now live in _data/ instead of being hardcoded.
• Replaced the “Under Construction” homepage and default About page with actual content.

Plan going forward is to use this for project writeups and the occasional life update, instead of letting it sit idle.
