/**
 * Industry cards
 *
 * One card component for the three places that list industries: the homepage
 * section, the industries hub, and the services hub. The markup comes from
 * ServicePageKit::industryCards() and the words come from
 * includes/service-page-kit/industries.php.
 *
 * The file stands alone. It carries its own color tokens, so it works on the
 * homepage, which does not load the Service Page Kit stylesheet.
 *
 * Contrast, computed against WCAG 2.1 by tests/test-industry-alignment.php:
 * every text color on every surface it sits on is at least 4.5 to 1, and the
 * control border and the focus ring are at least 3 to 1.
 *
 * The brand palette has no purple, and this file adds none.
 *
 * @see docs/industry-pages-alignment.html
