Inconsistent Button Styling: 'Sign In' button lacks rounded corners

[Rishabh6395]

Issue: The "Sign In" button on the homepage has squared corners, while the "Sign Up" button has rounded corners, leading to an inconsistent design.

Expected Behavior: Both buttons should have consistent styling, either both with or without rounded corners, to ensure a uniform look.
Steps to Reproduce:

1. Go to the website's homepage (provide URL if applicable).
2. Locate the "Sign In" and "Sign Up" buttons.
3. Observe the difference in corner styling between the two buttons.
