Asciimation content is out of date

[github-actions]

The scheduled content-freshness check found that src/index.html's film data no longer matches upstream (https://www.asciimation.co.nz/Blinkenlights/). The "Update film data" workflow has been triggered automatically to open a PR with the refresh. This issue will need to be closed manually once that PR is merged - the check doesn't auto-close it, to avoid closing an issue someone is still actively working.

Master already had the film-data update from #86 by the time this ran (issue was opened against a stale branch snapshot, not master) — the automated update workflow found nothing to do. Closing as not needed.
