Free npm downloads badge for any website

The free npm downloads badge that doesn't refetch an SVG every page load. Shields.io's npm badge is fetched 3rd-party. npm-stat.com is a separate site visitors have to leave for. This npm downloads badge is a 4 KB script tag — pulls the live download count from api.npmjs.org, caches it server-side for 6 hours, and shows 'npm 3.2M downloads / week' as a crisp pill in 7 themes. Free, no API key, no signup, supports scoped packages (@scope/pkg).
