Keeping up with frontier AI models is something I do by building with them rather than reading about them. They change fast enough that the only reliable way to know what they can and cannot do is to hand them real work and watch closely — where the output is right first time, where it needs correcting, and where it confidently gets something wrong.

This site is that experiment. Every page was built in conversation with Claude Cowork: I describe what I want, review what comes back, push on the parts that miss, and pick up the underlying HTML and CSS along the way. The interactive pieces — the Snake game and the orbital mechanics sandbox — came out of the same back-and-forth, including the physics checks behind the sandbox.

The stack is deliberately plain. Hand-written HTML and CSS with no framework, no build step and no dependencies; source in a GitHub repository; and Cloudflare Pages watching the main branch and redeploying on every commit. Static files served straight from the repo root, which keeps the whole thing legible enough that I can open any page and understand what it does.
