Access date for every file: 2026-11-01.

Licence text below is the visible Usage wording on the archive.org item page (the `rel="license"` link), not the API `licenseurl` alone.

`beat-132.mp3` is not sourced from anywhere: `scripts/make-beat.mjs` synthesises it (132 BPM, 10 s) and it ships under the same licence as the code (see LICENSE).
