/*
 * PDF Generator for WooCommerce – Premium Frontend Styles v2.3.0
 *
 * Design philosophy:
 *   1. Inherit from active WooCommerce/theme wherever possible
 *   2. Use CSS custom properties (--pgw-*) for plugin-specific branding
 *   3. Zero !important — styles are scoped under .pgw-* selectors
 *   4. Responsive-first with progressive enhancement
 *   5. Supports prefers-color-scheme for dark mode-aware themes
