# 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: Neon Tokyo
TYPE: Urban nightscape interface

MUST USE:
- Dark night sky background: bg-[#0a0a1a]
- Multi-color neon glows (not single-color)
- Primary pink: text-[#ff1493], border-[#ff1493]
- Cyan accent: text-[#00f0ff]
- Warm neon: text-[#ff6b00]
- Purple neon: text-[#bc13fe]
- Glow shadows with color: shadow-[0_0_20px_rgba(255,20,147,0.5)]
- backdrop-blur for glass/reflection effect
- font-bold uppercase tracking-wider for labels
- rounded-sm for subtle edge softness

MUST AVOID:
- Light/white backgrounds
- Low saturation or muted colors
- Regular shadows (shadow-md)
- Serif fonts (except for Japanese decorative text)
- Single-color neon palettes
- Corporate or overly clean layouts

COLOR RULES:
- Neon Pink: #ff1493 (primary)
- Night Sky: #0a0a1a (background)
- Cyan Neon: #00f0ff
- Warm Neon: #ff6b00
- Purple Neon: #bc13fe

DIFFERENCE FROM CYBERPUNK-NEON:
- Warmer, more organic feel
- Multi-color neon mixing (not cyan-dominant)
- Street photography aesthetic, not sci-fi
- Wet reflections, not scan lines

## Animation & Interaction Rules

- Rain-Slicked Reflections: Bottom reflection gradients should intensify on hover with higher opacity and mixed-color refraction.
- Signboard Flicker: Primary neon headings can use subtle irregular flicker to mimic aging street signage.
- Bleeding Glows: Hover state should expand pink/cyan/orange glow layers simultaneously so light bleeds at the edges.
- Damp Atmosphere: Transitions stay smooth (duration-300 to 500) to preserve wet-night ambience rather than sharp arcade motion.

# Neon Tokyo Design System

> Tokyo Kabukicho neon nightscape style with rain-slicked street reflections, layered neon signage, and cyberpunk urban night vibes. Unlike cyberpunk-neon's sci-fi feel, this leans toward authentic urban nightscapes.

## Design Philosophy

Neon Tokyo draws inspiration from the neon nightscapes of Tokyo's Kabukicho, Shinjuku, and Shibuya. Unlike Cyberpunk Neon's sci-fi futurism, this style is closer to authentic urban nightscapes -- rain-soaked streets reflecting layered neon signs, warm and cool colors intertwining on wet asphalt.

Core concepts:
- Urban nightscape: A near-black deep blue-gray base simulating Tokyo's late-night city skyline
- Neon signage: Multi-color neon lights layered together, with pink, cyan, orange, and purple flickering in alternation
- Wet reflections: Elements carry a subtle reflective quality, like neon reflections on rain-slicked streets
- Layered depth: Bright foreground and dark background, simulating the visual depth of city alleyways

The key difference from Cyberpunk Neon: Neon Tokyo is warmer, more organic, and closer to real photography aesthetics. It does not pursue cold technological vibes but instead captures the lonely romance of a late-night wanderer in a neon jungle.

Suitable for: nightlife apps, music streaming, streetwear brands, urban photography portfolios, Japanese izakaya menus.
