Footnotes

1. if these branch preview links are not working, please check the logs for the commit-based preview link. There is a character limit of 28 for the branch subdomain, as well as some other heuristics, described here for the sake of implementation ease in deploy-preview.yml, that algo has been omitted. The URLs are logged in the wrangler output, but it's hard to get outputs from a matrix job. ↩
