Seneroy is not a single page with a region toggle — it's a set of fully independent country modules. Choosing a country loads only that country's code, data, and features. Nothing crosses over.
Each module lives in its own folder (/ghana/, /california/) with its own index.html, manifest.json, and sw.js. There is no shared JavaScript, no shared data array, and no CSS class toggling between regions — a visitor to /california/ never downloads a single byte of Ghana code, and vice versa. This page is the only thing that knows both modules exist.
