/**
 * BUZZRFP Government Theme
 *
 * This stylesheet implements the BUZZRFP design system with:
 * - Government-friendly color palette (Navy, Blue, Red, Gold)
 * - SaaS-optimized admin panel colors (softened for daily use)
 * - Modern typography with Inter font family
 * - Status badges and semantic colors
 *
 * Design Strategy:
 * - Sidebar uses darker navy (#1E3A5F) for brand connection
 * - Main content uses softer tones for comfortable daily use
 * - Semantic status colors for quick visual understanding
