CLS & Text Logo in Main Navigation

I struggled with the CLS score of my site moonpicker.com; stuck and need help.

The case is I put the text logo of my site in the navigation bar but it affects the way it forms its final shape.

I think it loads longer (affecting CLS) due to lacking CSS that rules it.

The screenshot is here: https://prnt.sc/10ctvtg

While the additional CSS is the following:

body {
	margin: 0%; /* Space around site. */
	position: relative;
}

.no-sidebar .inside-article > *, 
.no-sidebar #comments,
.no-sidebar .paging-navigation {
	max-width: 700px;
	margin-left: auto;
	margin-right: auto;
}

button, html input[type="button"], input[type="reset"], input[type="submit"], a.button, a.button:visited,
.nav-links > * {
    border-width: 1px;
    border-style: solid;
    border-color: inherit;
}

.nav-links > * {
	padding: 5px 15px;
}

.entry-header {
	text-align: center;
}

.site-description {
	margin-top: 1em;
}

.post {
	margin-bottom: 4em;
}

.site-main .gallery, fieldset legend, p {
	margin-bottom: 2em;
}

/* Slideout navigation */

.slideout-navigation button.slideout-exit {
	font-size: 18px;
	margin-top: 5px;
}

.sf-menu > li.slideout-toggle {
	float: left;
}

.slide-opened .main-navigation.offside {
		transform: initial;
    position: absolute;
    top: 0;
    left: 0;
    height: 100%;
		z-index: 100 !important;
}

.slideout-overlay {
	background-color: rgba(0,0,0,0.1);
	z-index: 99;
}

#generate-slideout-menu .close-slideout.sfHover a {
	color: inherit;
}

.slideout-navigation .main-nav {
	border-bottom: 1px solid rgba(0,0,0,0.1);
}

.slideout-navigation .slideout-widget {
	padding: 15px 15px 0;
	font-size: 15px;
}

.site-logo {
width: 100%;
height: auto;
}
.site-header {
    min-height: 150px;
}

Thanks in advance.
