/**
 * Contact Central V2 - Design System 2026
 * Version: 1.1.0
 *
 * Design Specification: docs/design/DESIGN-001-Redesign.md
 *
 * 2026 Design Trends Applied:
 * - Softer Dark Mode: Mid-tone backgrounds (#0f172a, #1e293b) instead of pure black
 * - Typography-First: Variable fonts, clear hierarchy, reduced icon dependency
 * - Bento Grid: Modular, asymmetric layouts
 * - Purposeful Micro-interactions: Motion as guidance, not decoration
 * - Accessibility-First: WCAG AA compliant, motion controls, cognitive support
 * - Labels-Left Forms: Form labels positioned left of inputs (stacked on mobile)
 *
 * Note: Liquid Glass effects available but NOT used on sidebar (too grey).
 * Sidebar uses solid dark background with subtle purple gradient overlay.
