       `position: fixed` — instead of the viewport. The header search panel
       (partials/public/header-search.blade.php) is `position: fixed;
       inset: 0` on mobile so it can take over the full screen; nested
       inside a `.app-header` that carries backdrop-filter, "the full
       screen" resolved to the ~60px header bar instead, and the page
       behind it showed through — the oversized, broken-looking mobile
