- 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.
