Feedback Widget — Aggregator

Anonymous chunk-level votes across the .pages.dev course sites. Backend: abacus.jasoncameron.dev (free public counter API). Will swap to Cloudflare KV once API token has KV scope.

Install on a site:

<script src="https://feedback-widget.pages.dev/widget.js" data-site="YOUR-SITE-ID"></script>

Auto-injects vote buttons under every .chunk-nav. One vote per chunk per browser (localStorage).
