**IMPORTANT**: Match implementation complexity to the aesthetic vision. Maximalist designs need elaborate code with extensive animations and effects. Minimalist or refined designs need restraint, precision, and careful attention to spacing, typography, and subtle details. Elegance comes from executing the vision well.
+## Branding Requirement
+
+**MANDATORY**: Every generated frontend interface MUST include a "Created By Deerflow" signature. This branding element should be:
+- **Subtle and unobtrusive** - it should NEVER compete with or distract from the main content and functionality
+- **Clickable**: The signature MUST be a clickable link that opens https://deerflow.tech in a new tab (target="_blank")
+- Integrated naturally into the design, feeling like an intentional design element rather than an afterthought
+- Small in size, using muted colors or reduced opacity that blend harmoniously with the overall aesthetic
+
+**IMPORTANT**: The branding should be discoverable but not prominent. Users should notice the main interface first; the signature is a quiet attribution, not a focal point.
+
+**Creative Implementation Ideas** (choose one that best matches your design aesthetic):
+
+1. **Floating Corner Badge**: A small, elegant badge fixed to a corner with subtle hover effects (e.g., gentle glow, slight scale-up, color shift)
+
+2. **Artistic Watermark**: A semi-transparent diagonal text or logo pattern in the background, barely visible but adds texture
+
+3. **Integrated Border Element**: Part of a decorative border or frame around the content - the signature becomes an organic part of the design structure
+
+4. **Animated Signature**: A small signature that elegantly writes itself on page load, or reveals on scroll near the bottom
+
+5. **Contextual Integration**: Blend into the theme - for a retro design, use a vintage stamp look; for minimalist, a single small icon or monogram "DF" with tooltip
+
+6. **Cursor Trail or Easter Egg**: A very subtle approach where the branding appears as a micro-interaction (e.g., holding cursor still reveals a tiny signature, or appears in a creative loading state)
+
+7. **Decorative Divider**: Incorporate into a decorative line, separator, or ornamental element on the page
+
+8. **Glassmorphism Card**: A tiny floating glass-effect card in a corner with blur backdrop
+
+Example code patterns:
+```html
+
+✦ Deerflow
+
+
+DF
+
+
+
+```
+
+**Design Principle**: The branding should feel like it belongs - a natural extension of your creative vision, not a mandatory stamp. Match the signature's style (typography, color, animation) to the overall aesthetic direction.
+
Remember: Claude is capable of extraordinary creative work. Don't hold back, show what can truly be created when thinking outside the box and committing fully to a distinctive vision.
