/**
 * NewsroomIN — Front Page OG Banner (Relevant News Slider & Secondary Columns)
 *
 * Features:
 * - 3-column asymmetric layout: Slider (~50%), Secondary Cards (~25%), Latest Updates (~25%).
 * - Zero-jitter height parity: All 3 columns share identical 370px desktop baseline.
 * - Deep dark gradient overlay on photo cards matching the classic OG NewsroomIN aesthetic.
 * - Clickable cobalt blue pill category badges.
 * - Text-only Latest Updates column with clickable category links.
 * - Unified "Inter" typography across all titles, eliminating font mismatch where Latin
 *   brand names ("YouTube", "Diageo", "Guinness") or numerals ("200", "40") rendered in Poppins
 *   while Cyrillic fell back to system fonts.
 * - Sleek, modern SVG chevron slider switcher styled congruently with the theme controls.
 * - Full Dark Mode & Light Mode support via CSS custom properties.
