- Remove preview/rendered.js from .gitignore so the project works
out-of-the-box after clone (no Go required for static preview).
- Hide loading spinner when rendered.js is not found; previously
the spinner stayed visible forever because render() returned
early when 'rendered' was null.
- Regenerate rendered.js with all current template fixes.
