Are custom fonts hurting speed more than they help brand perception?

As an e-commerce business owner, I'm struggling to understand the performance impact of custom fonts on my online store. While I want my brand to look unique and professional, I've heard conflicting advice about whether custom typography actually helps or hurts my site's loading speed and overall user experience. I need a clear, data-driven perspective on balancing design aesthetics with technical performance, especially considering how critical page load times are for conversion rates and search engine rankings.
