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.
Rebuild header-slider card DOM/CSS against zib_header_slide + zib_icon_cover_card so shared/individual backgrounds, flex gutters, and badge icons match the reference theme.
Put hero main title/subtitle in search before_html (document flow),
move the search overlay outside the swiper as a sibling, and reset
search/slide-text positioning to zibll tops so title and search no
longer overlap.
