This page loads sentiment-plugin.js as a sibling file and wires it up
to four independent consumers — a slider, an inline text highlighter,
a stats row, and a live JSON viewer — all driven by the same
onScoreChange callback.
sentiment-plugin.js didn't load.
This example expects sentiment-plugin.js in the same folder.
Serve both files from a local web server, for example:
python3 -m http.server in the folder containing them.
