Hidden when there is one page. Buttons 32 px (44 px mobile), current page `--rc-sand` with `--ui-primary` border, disabled controls 40% opacity, focus ring 2 px `--ui-primary`. Page size and page live in the URL as `size` and `page`.
 
+Variant for Sites and Authors (no new component): when everything fits on one page the page-size select is hidden together with the controls and the footer shows only the count line "N sites" or "N authors" in `--ui-text-muted`. Loading dims the whole pager to 40% and disables it; the summary reads "Loading page N…". Sizes are unchanged: 5, 25, 50, 100.
