Visual Enhancements for Zero-Value Cards:

1. Red-tinted Background: Cards with zero values now have a soft red gradient background (#fff5f5 to #ffe0e0) with a red border
2. Subtle Shake Animation: Cards gently shake every 4 seconds to catch attention without being too disruptive
3. Shimmer Effect: A sliding shimmer animation creates movement across the card
4. Pulsing Glow: The cards have a pulsing box-shadow that creates a breathing effect
5. Enhanced Icons: Icon containers pulse and have a soft glow effect
6. Improved Call-to-Action Messages: Added emoji and more engaging text:
   - Services: "🚀 Get started! Create your first API service above!"
   - API Keys: "🔑 Secure your APIs! Generate an API key now!"
   - Roles: "🔒 Control access! Set up your first role!"
7. Animated Underline: The prompt text has a sliding underline animation
8. Dark Mode Support: All effects work in both light and dark themes

The combination of these effects creates a sense of urgency without being overly aggressive. The cards will definitely stand out when values are zero, encouraging users to take action and populate their DreamFactory instance with services, API keys, and roles.
