How this site is made.

A brief note on the tools, decisions, and principles behind every pixel of this portfolio.
/ˈkɒləfən/ — a brief statement at a book's end detailing its production. A publisher's colophon, adapted for the web.

This site is built with NextJs, deployed on Vercel, and designed in Figma. It even runs "green," producing just ~0.07g CO₂ per visit.
