/*
 * The page heading.
 *
 * WEB-1. These rules were written out three times -- identically, byte for
 * byte, in rankings.css, weekly.css and chart.css -- so changing the heading
 * meant changing it in three places and any page that got missed silently
 * drifted.
 *
 * The nav bar lived here too until WEB-12 moved it to nav.css: only four pages
 * load this sheet, and the nav is on every page.
 *
 * Loaded FIRST by the pages that use it, so a page sheet can still override.
 * That reordering is the risk this change carries and it was measured rather
 * than assumed -- see `test_no_rendered_element_matches_both_sides_of_a_
 * reordered_collision`.
