This Worker fetches the public Flag Counter country-details page, merges the CN, HK, MO, and TW visitor counts into one CN entry, and returns normalized labels and flag codes for the site statistics page.
Deploy from this directory with:
npx wrangler deploy
The default FLAG_COUNTER_DETAILS_URL points at counter TSy. Override it with a Wrangler variable if the counter changes. Configure the deployed /v1/country-stats URL in _config.yml as country_stats.endpoint before publishing the Jekyll site.
