/**
 * News & Reviews Page Styles (Modernized)
 *
 * ============================================================================
 * FILE LOCATION: /includes/css/pages/news.css
 * UPDATED: January 12, 2026 - v3: Added Companies sidebar + bottom spacer
 * ============================================================================
 *
 * This follows the same fixed-background approach as about.css:
 * - Fixed header (stays at top)
 * - Fixed footer (stays at bottom)
 * - Scrollable content area between them
 * - Fixed background (doesn't scroll)
 * - Fixed overlay (doesn't scroll)
 * - Transparent cards with backdrop-filter
 * - 3-column layout: Companies sidebar + Articles + Stats sidebar
 * - Responsive: Hides companies sidebar on screens < 1200px
