<!-- To enable micro-interactions, you would typically use JavaScript. 
     However, for the purpose of this request, some CSS-only micro-interactions 
     are simulated using Tailwind's `group` and `peer` modifiers, 
     and `hover` / `active` / `focus` pseudo-classes for basic animations. 
     More complex animations would require a JS framework like React/Vue/Angular, 
     or plain JS with Web Animations API or CSS keyframe animations. -->
