v1.27.2
Fixed
tests/contrib/test_unsplash_plugin.pyis now robust to the
developer having a.envcontainingBRAGI_UNSPLASH_ACCESS_KEY.
_env_file=Noneis passed toSettings()in both tests to
disable dotenv loading; the field defaults to None when the env
var is absent. CI was unaffected (no.envthere); local dev
was the only failure surface.
