# Publishes the HTML test report to Cloudflare Workers on every push to the
# default branch, so the "Test Report" badge in the README links to something
# current rather than to a workflow log.
#
# Requires an `apps/test-reports/` (or equivalent) directory with a
# wrangler.toml whose `assets.directory` is `dist`, and a root `test:report`
# script that writes the Vitest HTML reporter output there.
