 Page and page size live in the URL as page and size. Defaults (page 1, size 25) are omitted. Allowed sizes 5, 25, 50, 100. Search, tab or sort changes reset to page 1. Rows equal the page size; the frames draw at most 10 rows. The paginator hides when everything fits on one page; the summary stays. Mobile shows Previous, "Page N of M" and Next. Keyboard: Tab reaches page size, first, previous, each page, next, last; Enter or Space activates; the current page has aria-current="page"; ArrowDown opens the page-size list, Enter selects, Esc closes.
