Incorrect background color opacity

[Teraskull]

Hi,

Noticed that the destructive button background color does not match the shadcn color on hover.

shadcn:

franken-ui:

I assume this is unintentional, as all other Zinc theme colors and CSS variables seem to match the shadcn colors.

This happens in both version 1 and 2.

In version 1:

.uk-button-danger:hover {
    opacity: .9;
}

In version 2:

.uk-btn:hover {
    opacity: .8;
}

Shadcn does this, instead of just opacity:

.hover\:bg-destructive\/90:hover {
    background-color: hsl(var(--destructive) / .9);
}

But for the secondary button background color, shadcn uses 80% opacity:

.hover\:bg-secondary\/80:hover {
    background-color: hsl(var(--secondary) / .8);
}

Which means .uk-btn cannot have the same hover opacity for all buttons, since they differ.

I know this is a very minor nitpick, but I thought maybe this issue was missed.

Thanks for the great work!
