/*
  styles.css
  This file contains custom CSS styles for the PatentChainAI project. It complements Tailwind CSS and provides additional design elements for navigation, buttons, hero sections, cards, and more.
  
  Each section is labeled to help beginners understand which styles apply to which parts of the UI.
  You can use these styles in your React components by adding the corresponding class names.
