| 9 | </context> |
| 10 | |
| 11 | <design_philosophy> |
| 12 | Create a design that would win design awards. Avoid the "AI slop" aesthetic at all costs: |
| 13 | - NO purple/blue gradients on white backgrounds |
| 14 | - NO generic fonts (Inter, Roboto, Arial, system-ui) |
| 15 | - NO predictable hero-CTA-features-testimonials templates |
| 16 | - NO generic geometric shapes or abstract blobs |
| 17 | - NO stock-looking imagery or clichéd visuals |
| 18 | </design_philosophy> |
| 19 | |

| 33 | Build these sections with creative interpretation: |
| 34 | |
| 35 | 1. **Hero Section** |
| 36 | - A hook that creates immediate intrigue |
| 37 | - Interactive element that demonstrates capability |
| 38 | - Clear value proposition in ≤12 words |
| 39 | - Primary CTA: "<primary_cta>" |
| 40 | - Trust signals (logos, security badges) |
| 41 | |
| 42 | 2. **Problem/Solution Narrative** |
| 43 | - Tell a story, don't list features |
| 44 | - Use scroll-triggered reveals for dramatic effect |
| 45 | - Include real-world scenario visualization |
| 46 | |
| 47 | 3. **Product Showcase** |
| 48 | - Interactive demo preview or animated mockup |
| 49 | - Show the product in action visually |

| 87 | Implement these animation principles: |
| 88 | - **Page Load**: Orchestrated reveal sequence (0ms → 200ms → 400ms stagger) |
| 89 | - **Scroll**: Fade-in-up with subtle parallax on key visuals |
| 90 | - **Hover**: Scale transforms, color transitions, underline animations |
| 91 | - **Interactive**: Cursor-following effects, magnetic buttons |
| 92 | - **Background**: Subtle ambient motion (floating particles, gradient shifts) |
| 93 | </motion_design> |
| 94 | |
| 95 | <color_guidance> |
| 96 | If you choose a dark theme: |
| 97 | - Deep background: #0a0a0f to #12121a range |
| 98 | - Text: Pure white (#ffffff) for headlines, muted (#a0a0a0) for body |
| 99 | - Accent: ONE bold color used sparingly (electric cyan, hot coral, acid green) |
| 100 | |
| 101 | If you choose a light theme: |
| 102 | - Background: Off-white or cream (not pure white) |
| 103 | - Text: Deep charcoal (not pure black) |
| 104 | - Accent: Bold, unexpected (terracotta, forest, sapphire) |

| 110 | - Body: Readable with character (Source Serif Pro, Satoshi) |
| 111 | - Mono: JetBrains Mono, IBM Plex Mono for technical elements |
| 112 | |
| 113 | Avoid at all costs: Inter, Roboto, Arial, SF Pro, Open Sans |
| 114 | </typography_direction> |
| 115 | |
