Pagination

A controlled page navigator: prev / numbered buttons with collapsing … gaps / next. You own current (1-indexed) and react to onChange(page); the strip is computed from total items at pageSize per page:

val (page, setPage, _) = useState(1)
Pagination(current = page, total = 240, pageSize = 20, onChange = setPage)

// A compact "‹ 3 / 12 ›" bar:
Pagination(current = page, total = 240, pageSize = 20, simple = true, onChange = setPage)

siblingCount sets how many page buttons flank the current one before the rest collapse to …; simple swaps the full strip for a compact prev / “n / m” / next bar; disabled greys the control; Size scales it. The “which buttons to show” decision is a pure, exported function — paginationRange(current, totalPages, siblingCount) returning a Vector[PageItem] (Page(n) / Dots) — alongside pageCount(total, pageSize), so you can unit-test or reuse the logic without a DOM.
