/**
 * SEO Insights — Tools CSS
 *
 * Styles for the 6 SEO tool modules. Uses the theme's existing design
 * tokens (--color-primary, --color-bg-card, etc. from style.css) so
 * tools feel native rather than bolted-on, whether they appear on a
 * dedicated tool page, the homepage grid, or embedded in an article.
