Legacy Mount (data-mount-before)
Some CMS integrations only allow synchronous script injection. This page simulates the data-mount-before snippet by omitting a container and pointing the SDK at a script tag. Inspect the DOM to ensure the placeholder is inserted before the script and that warnings appear when the selector is invalid.
This harness omits a container and relies on data-mount-before semantics. The SDK inserts the embed right before the simulated loader script below.
