Juwan-Hwang/substrate ? reverse-engineered prompt

Build me a personal site platform called Aevum, with a polished public site and a solid codebase behind it.

I want the site to feel like a home base for my work, with three main areas: a visual knowledge and graphics section called Lattice, a space for runnable experiments and small demos called Crucible, and an Archive for articles, projects, and notes. The whole thing should feel modern, clean, and a little experimental, with strong typography, smooth navigation, and room for rich content.

Please set it up so the content side is easy to edit, the UI is reusable, and the project is organized like a real production app. Use the existing repo structure and make the main site work end to end, including the homepage, section pages, and a few nice starter examples. If you need to check current docs for any tools or frameworks, go ahead and look them up online.
