/**
 * F12 Design System - Announcements Shortcode Styles
 *
 * This file contains ONLY announcements-specific layout and decoration.
 * Typography, spacing, and component styles come from the design system.
 *
 * DESIGN SYSTEM COMPLIANCE:
 * ✓ Uses design system components (.f12-card--featured, .f12-feed--editorial)
 * ✓ No margins on components (spacing via f12-stack)
 * ✓ Token-driven values throughout
 * ✓ Minimal custom CSS
