GitHub Pages site for the transifex organization. It only exists to keep old
project-site URLs working after their repositories moved to other orgs:
/openapi/→https://api-docs.transifex.com/(the API reference, published fromxtm-group/openapi). Deep links keep their#tag/...fragment.
A path here is only served when no repository in this org publishes its own
site at the same path, so the redirect takes over once transifex/openapi has
moved. Do not set a custom domain on this site: that would also move every
remaining transifex.github.io/<repo> project site to that domain.
