/**
 * Patterns & Decorative Elements
 * This CSS file contains various background patterns and decorative elements
 * that can be applied throughout the website for visual interest.
 *
 * Usage Guidelines:
 * - Background patterns can be applied to sections or divs to add texture or visual interest.
 * - Decorative elements like circles, dots, and abstract shapes can be used as overlays or accents.
 * - Section dividers can be used to separate content sections with visual flair.
 * - Ensure that patterns and decorative elements do not overpower the main content.
 * - Use position helpers (e.g., .top-right, .bottom-left) to position decorative elements.
