# 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

STYLE: Cyberpunk Neon
TYPE: Futuristic sci-fi interface

MUST USE:
- Dark background: bg-[#0a0a0f] or bg-gray-950
- Neon glow shadows: shadow-[0_0_20px_rgba(0,255,255,0.5)]
- Text glow: style={{textShadow: '0 0 10px currentColor'}}
- Glowing borders: border border-cyan-400 shadow-[0_0_10px...]
- High saturation colors: cyan-400, fuchsia-500, yellow-400
- font-mono for tech text
- uppercase tracking-wider for labels

MUST AVOID:
- Light/white backgrounds
- Low saturation colors
- Regular shadows (shadow-md)
- Warm color schemes
- Large rounded corners (rounded-2xl+)
- Soft/friendly design language

COLOR RULES:
- Primary: Cyan (#00ffff)
- Accent: Magenta (#ff00ff)
- Background: Near-black (#0a0a0f)
- Text: White with glow
- Borders: Primary color with glow

SPECIAL EFFECTS:
- Scan line overlay for tech feel
- Pulsing elements with animate-pulse
- Glow intensifies on hover

---

## Animation Rules

### Interaction Physics
- **Unstable Neon**: Glow effects may pulse subtly. Use `animate-pulse` sparingly. NO high-frequency flickering that hurts readability.
- **Glitch Press**: Active state uses OFFSET translation + color inversion, NOT scale. Example: `active:translate-x-[2px] active:-translate-y-[1px] active:text-fuchsia-400`
- **CRT Scanline**: Cards increase scanline density/visibility on hover, simulating terminal scanning.
- **Fast & Raw**: Standard interactions use `duration-100` to `duration-150`. Only scan sweeps may use up to `duration-300`.

### Timing Guidelines
| Interaction | Duration | Easing |
|-------------|----------|--------|
| Button hover | 100-150ms | ease-out |
| Glow pulse | 2-3s | ease-in-out (loop) |
| Scan sweep | 150-300ms | ease-out |
| Glitch press | instant | — |

---

## Typography

| Element | Classes |
|---------|---------|
| Headers | font-mono font-bold uppercase tracking-[0.2em] |
| Labels | text-xs font-mono uppercase tracking-wider |
| Body | font-mono text-sm |
| Code/Data | font-mono tabular-nums |

---

## Forbidden Patterns

| Pattern | Reason |
|---------|--------|
| Light/white backgrounds | Destroys neon visibility |
| Low saturation colors | Loses cyberpunk intensity |
| shadow-md, shadow-lg | No blur shadows — only glow |
| Warm color schemes | Contradicts cold tech aesthetic |
| rounded-2xl, rounded-3xl | Too soft, not technical enough |
| Soft/friendly language | Breaks immersion |
| scale transforms on active | Use glitch offset instead |

---

## Self-Verification Checklist

Before outputting code, verify:
- [ ] Background is near-black (#0a0a0f or bg-gray-950)
- [ ] Neon glows use shadow-[0_0_Xpx_rgba(...)] format
- [ ] Text has textShadow glow effect where appropriate
- [ ] High saturation colors only (cyan, magenta, yellow, green)
- [ ] font-mono for all text elements
- [ ] Active states use glitch offset, NOT scale
- [ ] Rounded corners are rounded-sm or rounded-none
- [ ] Transitions are fast: duration-100 to duration-150

# Cyberpunk Neon Design System

> A futuristic cyberpunk style with neon glow effects, dark backgrounds, and high-tech UI elements. Ideal for games, tech products, and creative studios.

## Design Philosophy

Cyberpunk Neon style draws from cyberpunk sci-fi aesthetics, creating a futuristic feel through neon glow, dark backgrounds, and high contrast.

Core principles:
- Neon glow: Core elements stand out with glow effects
- Dark dominance: Near-black backgrounds make neon colors more striking
- High-tech feel: Grids, scanlines, and other elements enhance the tech atmosphere
- Color impact: Cyan, magenta, yellow, and other high-saturation colors

## [FORBIDDEN]

These classes are banned in this style. Check for them before returning code:

### Banned classes
- `bg-white`
- `bg-gray-50`
- `bg-slate-50`
- `shadow-sm`
- `shadow-md`
- `shadow-lg`
- `text-gray-900`
- `rounded-2xl`
- `rounded-3xl`

### Banned patterns
- matches `^bg-white`
- matches `^bg-gray-[1-3]`
- matches `^bg-slate-[1-3]`
- matches `^shadow-(?!\[)`
- matches `^rounded-[23]xl`

### Why they are banned
- `bg-white`: Cyberpunk uses dark backgrounds only
- `shadow-md`: Use neon glow shadows: shadow-[0_0_20px_rgba(0,255,255,0.5)]
- `rounded-2xl`: Keep corners subtle (rounded-lg max)

> WARNING: if your code contains any of the above, replace it before shipping.

- [ ] Card includes: `bg-gray-950 border border-cyan-400/30 rounded-lg`
- [ ] Input includes: `bg-gray-950 border border-cyan-400/30 rounded-lg text-cyan-400 font-mono focus:border-cyan-400 focus:shadow-[0_0_15px_rgba(0,255,255,0.3)]`

### Forbidden check
- [ ] Not using `bg-white`
- [ ] Not using `bg-gray-50`
- [ ] Not using `bg-slate-50`
- [ ] Not using `shadow-sm`
- [ ] Not using `shadow-md`
- [ ] Not using `shadow-lg`
- [ ] Not using `text-gray-900`
- [ ] Not using `rounded-2xl`

### Style rule check
- [ ] Use dark backgrounds bg-[#0a0a0f] or bg-gray-950
- [ ] Use shadow-[0_0_20px_rgba(0,255,255,0.5)] to create glow effects
- [ ] Text glow with [text-shadow:0_0_10px_currentColor]
- [ ] Glowing borders with border border-cyan-400 shadow-[0_0_10px_rgba(0,255,255,0.3)]
- [ ] Use scanline background effects for tech feel

### Style drift check
- [ ] Does not violate: Do not use light/white backgrounds
- [ ] Does not violate: Do not use low-saturation colors
- [ ] Does not violate: Do not use regular shadows like shadow-md (must use glow shadows)
- [ ] Does not violate: Do not use warm color schemes (unless for warning/error colors)
- [ ] Does not violate: Do not use overly large border radius rounded-2xl, rounded-3xl

### Delivery check
- [ ] Responsive layout holds on phone, tablet and desktop with no horizontal overflow
- [ ] Every interactive element has a visible focus state, an accessible name and a reduced-motion path
- [ ] Text contrast meets WCAG AA and colour alone never carries state
- [ ] The result is still recognizable at a glance as Cyberpunk Neon
