/**
 * Capital Chronicle - Typography System
 * 
 * This file implements the "Hybrid Typographic System" that serves as the
 * core brand identity element for the Capital Chronicle. The system uses
 * a dual-font hierarchy:
 * 
 * - Inter (Sans-Serif): For headlines, UI elements, and data points
 *   Caters to the "Data-Driven Professional" audience segment
 * 
 * - Source Serif Pro (Serif): For article summaries and body copy
 *   Caters to the "Strategic Reader" audience segment
