Rapid UI Tweaks for Prototype

I have a working high-figh prototype and need it polished within the next few hours. The scope is strictly UI: no new features or bug-hunting, just visual refinement. Primary focus • Typography – update font style, adjust sizes for hierarchy, and tighten line spacing so everything reads cleanly... (Budget: $12 - $30 SGD, Jobs: Figma, UI / User Interface)
