Pagination
Controllers paginate a relation and views render pagination_nav, styled to match the template.
<nav class="pagination" aria-label="Pages"><a rel="prev" aria-label="Previous" href="/docs/pagination?page=5"><</a><a href="/docs/pagination">1</a><a role="separator" aria-disabled="true">…</a><a href="/docs/pagination?page=5">5</a><a role="link" aria-disabled="true" aria-current="page">6</a><a href="/docs/pagination?page=7">7</a><a role="separator" aria-disabled="true">…</a><a href="/docs/pagination?page=50">50</a><a rel="next" aria-label="Next" href="/docs/pagination?page=7">></a></nav>
