/* Industries dropdown, for the pages whose styles are inline.
 *
 * The industry pages themselves get these rules from assets/industry.css, which
 * carries its own copy alongside the rest of its navigation. Everything else on
 * the site keeps its CSS in a <style> block in the page, so the dropdown needs
 * somewhere shared to live rather than being pasted into fourteen heads.
 *
 * Note where the mobile rules hang. Those pages do not agree on a breakpoint —
 * the hamburger appears at 720px on the home page, 760px on the articles and
 * 768px on the service pages — so a fixed media query here would be wrong on
 * two thirds of them, and between 721px and 768px the menu would render as a
 * floating white panel inside a slide-out drawer. The rules key off
 * .nav-links.open instead, which is the class each page's own script puts on
 * the drawer when the hamburger is pressed. That is true at exactly the widths
 * where the drawer exists, whatever each page has decided those are.
 *
 * Colours are written with fallbacks because a couple of pages define a
 * narrower set of custom properties than the home page does.
