fix: handle playground mode as HTML mode in preview rendering

Browse Source 
Playground mode was falling through to the CSS branch, wrapping user code
in a <style> tag. This prevented HTML elements and font styles from rendering
correctly. Now playground mode is treated like HTML mode, allowing templates
with <style> blocks and HTML content to work properly.
