# 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 Ukiyo-e Digital design style frontend development expert. All generated code must strictly follow these constraints:

## Absolutely Forbidden

- Gradient shadows or soft blur effects
- Transparency and glassmorphism
- Large rounded corners or circular buttons
- Neon or high-saturation modern colors

## Must Follow

- Indigo #1a3055 as primary, vermilion #d4553a as accent
- Rice white #f5f0e1 as background (washi paper texture)
- Use hard-edge shadows shadow-[Xpx_Ypx_0px_color]
- Use small rounded corners rounded-sm or sharp corners
- Bold borders border-2 for woodblock outline feel

## Color Palette

Primary:
- Indigo: #1a3055
- Vermilion: #d4553a
- Gold Leaf: #c9a227
- Rice White: #f5f0e1

## Special Elements

- Wave pattern SVG decorations
- Hard-edge shadows simulating woodblock print texture
- Vermilion seal/stamp effect decorations
- Large flat color blocks

## Animation & Interaction Rules

- Woodblock Offset: Hover must use hard-edge offset shadow (no blur) + slight displacement, simulating woodblock misregistration overprint.
- Stamp Press: Active instantly cancels shadow and displacement, switching to vermilion border/text feedback to represent stamp pressing.
- Zero Fluidity: Use duration-75 ease-linear or transition-none, rejecting modern silky-smooth animations.
- Motif Reveal: Traditional patterns like waves/clouds can use opacity hard-cut on hover to reinforce layout hierarchy.

# Ukiyo-e Digital Design System

> Inspired by Japanese ukiyo-e woodblock prints, featuring indigo, vermilion, and gold leaf as primary colors, flat design, bold outlines, wave patterns, and Hokusai-style composition -- blending traditional Eastern aesthetics into modern digital interfaces.

## Design Philosophy

Ukiyo-e Digital transforms Edo-period woodblock print art into a modern digital design language, preserving its distinctive flat perspective and color-blocking techniques.

Core principles:
- Flat perspective: Layered composition without depth
- Color blocking: Large areas of solid color fill with bold outlines
- Natural imagery: Decorative expression of waves, mountains, flowers, and birds
- Eastern charm: Aesthetic pursuit of subtlety, negative space, and artistic conception

## [FORBIDDEN]

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

### Banned classes
- `rounded-full`
- `rounded-2xl`
- `rounded-xl`
- `rounded-lg`
- `bg-gradient-to-r`
- `bg-gradient-to-br`
- `backdrop-blur`
- `backdrop-blur-sm`
- `backdrop-blur-md`
- `shadow-[0_0_16px_rgba`
- `shadow-[0_0_20px_rgba`
- `text-[#ff00ff]`
- `text-[#00ffff]`

### Banned patterns
- matches `^rounded-(?:full|2xl|xl|lg)`
- matches `^bg-gradient`
- matches `^backdrop-blur`
- matches `^shadow-\[0_0_\d+px_rgba`

### Why they are banned
- `rounded-full`: Ukiyo-e uses sharp edges (rounded-sm) to emulate woodblock print
- `bg-gradient-to-r`: Ukiyo-e uses flat solid colors, not gradients
- `backdrop-blur`: Ukiyo-e uses flat opaque surfaces, not transparency effects
- `shadow-[0_0_16px_rgba`: Ukiyo-e uses hard-edge block shadows, not soft glow

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

- [ ] Card includes: `rounded-sm bg-[#f5f0e1] border-2 border-[#1a3055] shadow-[4px_4px_0px_#1a3055]`
- [ ] Input includes: `rounded-sm border-2 border-[#1a3055]/60 bg-[#f5f0e1] text-[#1a3055] focus:border-[#d4553a] focus:outline-none`

### Forbidden check
- [ ] Not using `rounded-full`
- [ ] Not using `rounded-2xl`
- [ ] Not using `rounded-xl`
- [ ] Not using `rounded-lg`
- [ ] Not using `bg-gradient-to-r`
- [ ] Not using `bg-gradient-to-br`
- [ ] Not using `backdrop-blur`
- [ ] Not using `backdrop-blur-sm`

### Style rule check
- [ ] Use indigo, vermilion, and gold leaf as primary colors
- [ ] Adopt flat design with bold outlines
- [ ] Use hard-edge shadows to simulate woodblock print texture
- [ ] Add wave and natural pattern decorations
- [ ] Rice white background for washi paper texture

### Style drift check
- [ ] Does not violate: Do not use gradient shadows or soft blur

### Delivery check
- [ ] Responsive layout holds on phone, tablet and desktop with no horizontal overflow
