I noticed that some CSS was removed, including text-decoration: none;. Because of this, the display now looks like this, which doesn’t look good. Also, the hover state and the normal state have the same color, which makes the UI look poor.

@nikunj8866 Thanks for working on this.

Please note that only the color needs to be changed here. Any other changes are outside the scope of this ticket.

[nikunj8866]

I've added text-decoration: none; and set the link color to match the default theme color.

[shail-mehta]

The login page link hover color is aligned with the new theme color scheme.✅

The default color has changed. This is not the style that was expected.
