/**
 * Last Update: 2026-04-28
 * File: assets/frontend/css/news-frontend.css
 * Description: News index, list-by-type, hero carousel, card, grid, pagination
 *
 * v3 changes (2026-04-28):
 *   - Hero is now a CAROUSEL (1 visible slide, fades) with side panel of all 4 rows
 *   - Side panel shows ALL 4 rows with active highlight that syncs with carousel
 *   - Removed split layout from "first section" — every section now uses 4-col grid
 *   - Added .fe-news-feature__* family for the carousel + side panel
 *   - Removed: .fe-news-section__split, .fe-news-section__main,
 *              .fe-news-section__aside, .fe-news-grid--3, .fe-news-card-compact*
 *
 * Design rules:
 *   - No hex colors — use CSS variables from tokens-frontend.css
 *   - Mobile-first responsive
