/**
 * Article Components (Insights & Case Studies)
 *
 * The single insight and single case study pages are built from the same
 * markup and this one stylesheet: 3-column layout (table of contents rail,
 * article, right rail), callout, numbered points, related cards and the
 * conference band. Components only case studies fill (key figures, company
 * facts, logo hero) are drawn in the same style.
 *
 * Fonts and colors come only from the --whu-* variables that
 * whu_article_theme_vars_css() (includes/article/article-functions.php)
 * builds from the theme options, so the pages follow the site's own rules:
 *   article title      → H2 option     section titles → H4 option
 *   labels / eyebrows  → H6 option     lead text, quotes → quote option
 *   body text          → content option, text color
 *   dark surfaces      → header/footer blue
 * The few values below that have no theme option are copied from existing
 * site components (noted next to each).
