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

# 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 Holy Grail Layout expert. All generated code must strictly follow these constraints:

## Layout Structure

Five regions:
1. Header: Fixed top, brand + navigation
2. Left Sidebar: Fixed width, navigation menu
3. Main Content: Fluid width, primary content
4. Right Sidebar: Fixed width, auxiliary information
5. Footer: Fixed bottom, copyright information

## Implementation Rules

- Use Flexbox: outer flex flex-col min-h-screen
- Three-column area: flex flex-1
- Sidebars: fixed width w-60 / w-64 flex-shrink-0
- Main content: flex-1 min-w-0
- Header: sticky top-0 z-50
- Equal-height columns: three columns auto equal height

## Responsive

Large screens (>1024px): Full three columns
Medium screens (768-1024px): Hide right sidebar
Small screens (<768px): All columns stack vertically

## Animation & Interaction Rules

### Content Supremacy (Card Float)
- Cards in main content: hover:-translate-y-0.5 hover:shadow-md -- minimal, non-distracting float
- NEVER use hover:-translate-y-2 or larger (breaks reading focus)
- Transition: duration-150 ease-out (crisp productivity tool rhythm)

### Navigation Anchoring (Sidebar Links)
- Inactive nav items: hover:border-l-2 hover:border-[#3b82f6] hover:bg-gray-50 -- left-border highlight ONLY
- NEVER add vertical displacement to sidebar nav (anchoring feel requires stability)
- Active item: bg-[#3b82f6]/10 text-[#3b82f6] -- always-visible active state

### Crisp Performance (Duration Standard)
- All transitions: duration-150 ease-out -- productivity tools must feel instant
- NEVER exceed duration-200 for any interactive element

### Button Physics
- Hover: hover:-translate-y-0.5 hover:shadow-[0_4px_10px_rgba(59,130,246,0.4)]
- Active: active:scale-[0.98] active:translate-y-0 active:shadow-none -- tactile micropress
- Focus: focus:ring-2 focus:ring-[#3b82f6] focus:ring-offset-2 (WCAG 2.1 AA)

## Self-check

1. Header fixed at top
2. Three columns equal height
3. Main content area is fluid
4. Sidebars have fixed width
5. Footer always at bottom
6. Responsive collapsing works correctly
