Maybe try a more modern approach?" + +**Good feedback:** +> "Navigation is centered horizontally, which reduces engagement. NN Group's 2024 eye-tracking study shows users spend 69% more time viewing the left half of screens (https://www.nngroup.com/articles/horizontal-attention-leans-left/). Move nav to left side with `justify-content: flex-start`. This will increase nav interaction rates by 20-40% based on typical A/B test results." + +**Bad feedback:** +> "Colors are boring, try something more vibrant." + +**Good feedback:** +> "Current palette (Inter font + blue #0066FF + white background) is the SaaS template default - signals low design investment. Users make credibility judgments in 50ms (Lindgaard et al., 2006). Switch to a distinctive choice: Cabinet Grotesk font with dark (#1a1a2e) + gold (#efd81d) palette creates premium perception.
