AKSRT loads BS5 (.navbar --bs-navbar-padding-y:.5rem) while zibll uses
BS3 without it; that alone added ~16px. Zero BS navbar pad, keep only
.header 8px 20px (mobile 0 8px), horizontal CTA margins, tighter mobile
logo/toggle row.
Drop forced 34px CTA chips and container min-height:50 that inflated
or shrank the bar vs zibll. Restore .navbar-but .but to 0.8em / 0.3em
1em / margin 0.4em; keep logo 36px, header pad 8px 20px, fixed reserve 88px.
Live header uses .navbar-form.navbar-but without .navbar-but-cluster;
remove em padding/height:auto/min-height calc that grew chips on press
and override .but.radius padding so publish/VIP stay fixed size.
Center FA icons in toggle-radius/btn chips, restore menu-item title flex baseline, and match CTA/logo vertical alignment so top bar text and icons no longer drift.
Align nav-fixed geometry with zibll: only .slide-header pulls under the bar; restore card container gutters so home overlay cards match other page types.
Desktop was rendering .mobile-header / .mobile-navbar in document flow
because Bootstrap 5 has no visible-xs-block and drawer CSS only ran
inside max-width:767px. Hide drawer shell by default; only show as fixed
off-canvas on small screens. Also fix orphan CSS rules in navbar-core,
give .navbar-search position:fixed so the overlay never reserves height.
