Parent test page for the embed widget against certainteed production (colorview.certainteed.com).
NOTE: src intentionally uses the CORRECT canonical widget host (widget.renoworks.com/bundle.js). The snippet generated by the prod registration page instead emits colorviewapi.certainteed.com/bundle.js, which 404s — that is the known snippet-generation bug for vanity API hosts. This harness proves the embed itself works end-to-end when the src is right.
