/**
 * Education News Feed v1.2 – frontend styles
 *
 * Default "list" layout mirrors the reference design: light gray section,
 * thumbnail on the left, and on the right the title, an icon meta row
 * (source + date), a 3-4 line excerpt and an outlined "Read More" button.
 *
 * All colors are driven by CSS custom properties so the widget, shortcode
 * and admin settings can override them per instance:
 *   --enf-accent      accent color (buttons, hover states)
 *   --enf-card-bg     card background (grid cards + detail page)
 *   --enf-section-bg  section background (list wrapper)
 *   --enf-radius      corner radius
