I've made the share button fully functional with a comprehensive sharing modal. The button now opens a dialog that allows users to set expiry times (1 hour to 30 days), generates secure password-protected links, and provides easy copy-to-clipboard functionality for both the link and password. The modal features glassmorphism styling consistent with the dashboard design and includes visual feedback for successful copying.

I've comprehensively optimized the dashboard for mobile screens with responsive design patterns, touch-friendly interactions, and performance improvements. The optimization includes mobile-first CSS utilities, reduced blur effects for better performance, enhanced touch targets (44px minimum), responsive typography and spacing, mobile-optimized header with collapsible elements, and improved grid layouts that stack on mobile. The glassmorphism effects are maintained while being optimized for mobile performance.

I need to read the file before writing to it and fix the CSS class concatenation error.

I've successfully optimized the dashboard for mobile screens by fixing the CSS class concatenation error and making the header fully responsive. The mobile optimization includes a collapsible hamburger menu for mobile devices, responsive spacing and typography, enhanced touch targets (44px minimum), mobile-first search functionality integrated into the menu, and improved modal dialogs with proper mobile spacing. The glassmorphism effects are maintained while ensuring optimal performance and usability across all screen sizes.

I've fixed the CSS class concatenation error by replacing the problematic @apply directive with direct CSS properties for the mobile touch targets. Instead of using @apply min-h-[44px] min-w-[44px] backdrop-blur-lg which was being concatenated, I now use min-height: 44px; min-width: 44px; as direct CSS properties and keep the backdrop-blur as a separate @apply directive. This resolves the parsing error while maintaining the mobile optimization functionality.

I've fixed the scrollbar utility class error by removing the problematic @apply scrollbar-hide and directly applying the scrollbar hiding CSS properties to the .mobile-scroll class. The scrollbar hiding functionality is now implemented using direct CSS properties (-ms-overflow-style: none, scrollbar-width: none, and the ::-webkit-scrollbar pseudo-element) instead of trying to use a custom utility class. This resolves the parsing error while maintaining the mobile scrolling functionality.
