/*
 * Supply Chain Intelligence & Situation Report Hub — base styles.
 *
 * Aesthetic principles:
 *   1. Restraint with the accent — gold appears on actions, status, key
 *      moments. Not on every border or hover surface.
 *   2. Generous whitespace. Padding is the cheapest design upgrade.
 *   3. Typographic hierarchy via weight + size, not color saturation.
 *   4. Hairline borders. Depth comes from soft shadow, not visible edges.
 *   5. Sharper corners (4-8px) for editorial feel. No pill shapes.
