* Description: This is the dedicated stylesheet for the "Notice Board" section of
*              "Madhurima Mindscape". It defines the visual presentation of dated
*              notice cards, including categorized announcements, blog updates,
*              feature highlights, and optional navigation links.
*              The stylesheet uses a flexible, centered layout with glossy card effects
*              to maintain a consistent and visually appealing appearance across
*              different screen sizes.
* Version: 1.0
* GitHub Repository: https://github.com/madhurimarawat/Madhurima-Mindscape
* Issues/Bugs: For any issues or bugs, please visit the GitHub repository issues section.
* Comments:
    - The Notice Board layout is fully responsive, adapting to desktop, tablet, and mobile screens.
    - Flexbox is used to organize dated notice groups and their respective content sections.
    - Individual notice cards feature dashed gradient borders, translucent backgrounds,
      subtle shadows, animated glowing effects, and glossy shine transitions.
    - Notice groups display their corresponding dates above each notice card.
    - Blog and Features sections use consistent heading styles and spacing.
    - Individual notice items feature subtle hover effects and smooth background transitions.
    - Notice titles, icons, descriptions, and optional links maintain consistent alignment.
    - The notice board supports conditional visibility through the HTML hidden attribute.
    - Accessibility features include reduced-motion support for animated effects and transitions.
* Dependencies:
    - CSS Custom Properties: Uses theme variables such as --background-color, --text-color,
      --h2-color, and --link-color for consistent styling across light and dark themes.
    - Custom CSS: index.css, contents.css.
    - Font Awesome 5.15.4: Provides icons used within notice headings and individual notice titles.
    - Custom JavaScript: Dynamically manages notice board visibility and content presentation.
