Site refresh: Eleventy, GitHub Pages, and the same resume.json

This site now builds with Eleventy from Markdown and Nunjucks templates. The resume continues to come from the root resume.json (JSON Resume schema), so you only maintain one structured file for /resume/ and any future exports.

Next posts here will focus on AI-assisted software engineering—reviews, tests, security, and team norms—alongside occasional Unreal Engine and systems notes.
