Can customers self-host the Tailor serving script?

Tailor's managed script keeps delivery, experiment configuration, tracking, and updates version-compatible without requiring customers to host or manually update script assets. Live changes made in Tailor are reflected in the edge-cached serving script without extra round trips at request time, which is critical for low-latency serving. The script is also tightly coupled with the backend for experiment payloads, element signatures, and event tracking.
