   Sticky table headers — Safari-safe.
   Safari (incl. macOS 14 / iOS 16) does not honour position:sticky on
   <thead> or <tr>; the rule must live on <th> cells. Apply this class to
   the <table> element and the header cells will stick to the top of the
   nearest scrollable ancestor in every browser.
