AI Implementation

Copy the Hard Prompt first, then use the spec when needed

Use the Hard Prompt by default to generate UI. Use the Design Spec to understand, modify, and review the style. Use the Creative Brief for early exploration.

Hard Prompt

Use this by default: copy it, append the concrete requirement, and let AI generate consistent production UI.

When to use

When AI should generate UI directly
When repeated outputs must stay consistent
When style drift is the main risk

How to use

Copy the full prompt
Append the concrete requirement
Review against forbidden rules and UI states

style_slug: ukiyo-e-digital
style_source: /styles/ukiyo-e-digital

# 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.

## Absolute Bans (Match and Refuse)

If any of the following patterns appear, it is a style violation — rewrite without exception.

- use gradient shadows or soft blur
- use transparency and glass effects
- use Western-style rounded corners and circular buttons
- use neon or high-saturation modern colors
- use spring-bounce or modern app silky-smooth animations
- use soft shadows and glassmorphism that break the woodblock's crisp texture

## Self-Check (Verify Before Shipping)

If any item fails, the style has drifted — fix before shipping.
