    Overall, the design looks clean and professional. Colors and fonts are good and match the brand. Navigation is mostly intuitive. On mobile, the login screen’s input fields feel a bit tight. “Recent Wins” section could be slightly bigger to stand out. It would be helpful to have a confirmation message...
