Create a fully responsive and modern React component for “Sync Space” to display when no video is active. Include the ongoing meeting duration, action buttons with sleek icons for copying the invite link or space ID, and sending invites via email. Add a placeholder graphic with a motivational tagline like “Welcome to Sync Space - Stay connected, stay productive.” Use modern icons and subtle animations to give it a clean, polished look, and ensure the design adapts seamlessly across all devices.
