# The Unit Circle — an interactive narrated explorable

A lesson that is a live scene driven by a recorded voiceover: play it, or grab
the red point and scrub the angle yourself at any time and watch the cosine
recompute, then glide back to whatever the narration has reached.

Built with [narrable](https://github.com/) — narrated explorables authored from
a single text script. Available in **English** (default) and **French**
(append `?lang=fr` to the URL).

This is a static Space: the entire lesson is a self-contained bundle
(`index.html` + player JS + per-language `tracks.json`, captions, and audio).
No server-side anything.
