/**
 * Cre8tive Hands — Site Base Template Styles
 * ===========================================
 * Authority stylesheet for site-wide look, feel, and identity.
 * Based on ecards.html. Use this as the single source for:
 * - CSS variables (colors, spacing, shadows)
 * - Body background and typography
 * - Navbar, mobile menu, footer
 * - Base layout utilities
 *
 * All pages that use the site template should:
 * 1. Link to site-base.css first
 * 2. Then link to any page-specific stylesheets
