One hour to launch FontViz! Any last minute tips?

Hey PH Fam, With just 1 hour to go until the FontViz (https://fontviz.app/) launch on Product Hunt, I'd really appreciate any last minute advice or tips from experienced launchers. As a first-time maker, I want to make sure I give FontViz the best possible chance at success. What are some effective strategies you'd recommend for building early traction, engaging with the PH community, or maximizing visibility on launch day? Any insights would be incredibly valuable right now. Thank you in advance for sharing your wisdom!
