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=21"><</a><a href="/docs/pagination">1</a><a role="separator" aria-disabled="true">…</a><a href="/docs/pagination?page=21">21</a><a role="link" aria-disabled="true" aria-current="page">22</a><a href="/docs/pagination?page=23">23</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=23">></a></nav>
