Could you build this?
Partial The site and timeline visualization are easy to vibe-code, but the value depends on a curated, sourced register of 67 governments' official guidance that must be researched and kept current.
What it would actually take: The front end is a static or lightweight web app with a timeline and globe visualization, which is straightforward to build. The hard part is compiling and continuously verifying primary-source government guidance across many countries and dating each change. That requires research labor, source-verification discipline, and an update process, not deep engineering.
