Lopecode is a document you can double-click or throw on the web. It’s readable prose and a live programming environment. It resists bit-rot because it’s a local-rst, single HTML file that works without network. It’s a tool-for-thought and a distribution format: a reactive runtime that self-serializes with all dependencies bundled. The core is a tiny UI-less microkernel; features are userspace modules you can inspect, edit, and change live. It’s made for experimentation: extremely extensible, engineered to be fast (no network round trips), durable (plain-text, git-friendly), and immediate — change code and see the system update in place.
