Overview
Detects changes on a webpage: fetches a URL, strips HTML to plain text, computes a SHA-256 hash, and (when given a previous hash or text) returns a changed flag plus added/removed line lists. Optional CSS selector scopes the diff to one region. No login required; follows redirects. Use it as a website change monitor, content diff, page-watch, visualping-style monitor, price-page monitor, status-page watcher, or TOS-policy diff.
