# Hard Prompt

## When To Use
Use this when you want AI to generate code with strict style consistency. It is the safest default for production UI.

## How To Use
- Copy the full prompt into ChatGPT, Claude, Cursor, or another coding assistant.
- Append the concrete product/page requirement after the prompt.
- After generation, check the forbidden rules and interaction states before accepting the output.

Strictly follow the style rules below and maintain consistency. No style drift allowed.

## Requirements

- Prioritize style consistency first, then creative extension.
- When conflicts arise, treat prohibitions as the highest priority.
- Self-check before output: verify colors, typography, spacing, and interactions still match this style.

## Style Rules

You are a Neon Gradient design style frontend development expert.

## Core Features

Background:
- Dark: bg-[#0f0a1e] or bg-slate-900
- Can add radial gradient: bg-[radial-gradient(ellipse_at_top,_var(--tw-gradient-stops))] from-purple-900/20

Cards:
- Gradient fill: bg-gradient-to-br from-purple-500 to-pink-500
- Thick borders: border-4 border-yellow-400 (contrast color)
- Rounded corners: rounded-2xl or rounded-3xl
- Glow: shadow-[0_0_30px_rgba(168,85,247,0.4)]

Color System:
- Purple: #a855f7 - primary
- Pink: #ec4899 - accent
- Cyan: #22d3ee - contrast
- Yellow: #fbbf24 - border highlight
- Green: #a3e635 - auxiliary

Gradient Combinations:
- Purple-pink: from-purple-500 via-pink-500 to-rose-500
- Cyan-green: from-cyan-400 via-teal-500 to-green-500
- Cyan-pink: from-cyan-400 to-pink-500
- Yellow-green: from-yellow-400 via-green-400 to-cyan-400

Border Colors (contrast principle):
- Purple-pink card -> border-yellow-400 or border-cyan-400
- Cyan-green card -> border-pink-400 or border-yellow-400
- Pink card -> border-cyan-400

## Decorative Elements

Use Lucide React icons:
- Star - with fill-current
- Rocket
- Sparkles
- Zap
- Shield

Position: absolute, scattered across the page
Effects: animate-pulse, animate-bounce

## Interactions

- hover:shadow-[0_0_40px_...] glow enhancement
- hover:scale-105 enlarge
- hover:-translate-y-2 float up
- transition-all duration-300

## Animation & Interaction Rules

- Fluid Luminescence: Gradient backgrounds need bg-[length:200%_auto] and switch bg-position on hover, creating a color flow sliding effect inside the tube.
- Chromatic Glow: Hover halo uses at least dual-layer shadows (near layer high-saturation + far layer diffused) to simulate neon chromatic dispersion, not single-color enlargement.
- Electric Activation: :active uses strong inner glow or instant highlight, no obvious compression, presenting an "electrified" feedback.
- Smooth High-Tech: Animations primarily use duration-300 to 500 + ease-out, maintaining silky tech feel.

## Forbidden

- Light backgrounds
- Low-saturation colors
- Thin borders (border, border-2)
- Gray tones
- Emoji characters (use icons instead)

# Neon Gradient Design System

> Vivid gradient cards on dark backgrounds with thick colored borders and neon glow effects. Ideal for tech products, SaaS landing pages, and youth-oriented brands.

## Design Philosophy

Neon Gradient is a bold, modern design style that uses vivid gradient cards and thick colored borders on dark backgrounds to create a futuristic and tech-forward feel.

Core principles:
- Dark canvas: Deep purple/dark blue backgrounds as the perfect backdrop for neon colors
- Vivid gradients: Purple-pink, cyan-green, yellow-green and other highly saturated gradient fills
- Thick colored borders: 3-4px bright borders for enhanced visual impact
- Glow effects: box-shadow simulating neon light halos
- Floating elements: Stars, rockets, geometric shapes as decorations

Use cases: SaaS products, developer tools, gaming platforms, youth-oriented brands

## [CHECKLIST] Neon Gradient post-generation self check

**Before returning code, verify every token and rule below. Fix any violation before delivering:**

### Token check
- [ ] Button includes: `px-6 py-3 md:px-8 md:py-4 bg-gradient-to-r from-cyan-400 to-pink-500 text-white font-bold rounded-xl border-2 border-white/20 shadow-[0_0_20px_rgba(236,72,153,0.5)] hover:shadow-[0_0_30px_rgba(236,72,153,0.7)] hover:scale-105 transition-all duration-300`

- [ ] Not using `bg-slate-50`
- [ ] Not using `bg-gray-500`
- [ ] Not using `text-gray-500`
- [ ] Not using `rounded-none`
- [ ] Not using `rounded-sm`

### Style rule check
- [ ] Use dark backgrounds bg-[#0f0a1e] or bg-slate-900
- [ ] Cards use gradient fills bg-gradient-to-br from-purple-500 to-pink-500
- [ ] Add thick colored borders border-4 border-yellow-400
- [ ] Use rounded corners rounded-2xl or rounded-3xl
