Hello,
The difference in font rendering between your HTML and WooCommerce sites may be due to the way the fonts are loaded. If your HTML site loads the font locally while your WordPress site pulls it from Google Fonts, variations in rendering can occur.
To ensure consistency:
Go to Theme Settings > Typography and check the font settings.
If your HTML site uses a locally hosted font, upload the same font file to your WordPress site. You can do this via Theme Settings > Typography > Custom Fonts: https://xtemos.com/docs-topic/how-to-upload-custom-fonts/
Apply the same font weight and style to match both sites.
Best Regards,
