# 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: Geometric Bold
TYPE: Bold artistic design with strong shapes

MUST USE:
- Solid color blocks: bg-black, bg-white, bg-red-500, bg-blue-600
- Regular geometric shapes: circles, squares, triangles
- Large typography: text-6xl, text-8xl, text-[10rem]
- Absolute positioning for overlapping elements
- Corners: rounded-none OR rounded-full only
- Rotation for dynamics: rotate-12, rotate-45
- Limited palette: black, white + 1-2 accent colors

MUST AVOID:
- Gradients
- Soft/low contrast colors
- Medium border-radius (rounded-lg)
- Shadows
- Too many colors (max 3-4)
- Symmetrical/conventional layouts

COLOR RULES:
- Base: Black and White
- Accents: Primary colors (red, blue, yellow)
- Maximum 3-4 colors per design

TYPOGRAPHY:
- Headings: font-black uppercase
- Labels: text-xs tracking-[0.3em]
- Numbers: Often used as design elements

## Animation & Interaction Rules

- Blocky Impact: Interactions use solid color hard-cuts and short displacement feedback, avoiding soft opacity transitions.
- Shape Snapping: Geometric decorations can instantly rotate/scale on hover, creating a structural mutation feel.
- Heavy Press: Active state prefers displacement and layer rebound to express pressing, not relying on soft scaling.
- Linear & Fast: Uniformly use duration-100 + ease-linear, rejecting spring feel and slow trailing.

# Geometric Bold Design System

> Bold geometric design with strong shape contrasts, vivid color blocks, and dynamic compositions. Ideal for art exhibitions, design agencies, and creative brands.

## Design Philosophy

Geometric Bold style is influenced by Bauhaus and Constructivist art, creating visual impact through simple yet powerful geometric shapes.

Core principles:
- Shape first: Geometric shapes are the core design language
- Bold contrast: Strong color and shape contrasts
- Dynamic balance: Create visual tension through asymmetry
- Artistic expression: Every page is a work of art

## [FORBIDDEN]

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

### Banned classes
- `shadow-sm`
- `shadow`
- `shadow-md`
- `shadow-lg`
- `shadow-xl`
- `bg-gradient-to-r`
- `bg-gradient-to-b`
- `bg-gradient-to-l`
- `rounded-lg`
- `rounded-xl`
- `rounded-2xl`
- `text-gray-300`
- `text-gray-400`
- `bg-gray-100`
- `bg-gray-200`
- `opacity-50`
- `opacity-60`
- `opacity-70`
- `font-light`
- `font-normal`

### Banned patterns
- matches `^shadow-(?!none)`
- matches `^bg-gradient-`
- matches `^rounded-(?:sm|md|lg|xl|2xl|3xl)$`
- matches `^opacity-(?:[1-6]0)$`
- matches `^font-(?:light|thin|normal)$`

### Why they are banned
- `shadow-md`: Geometric Bold uses no shadows - pure flat shapes only
- `bg-gradient-to-r`: Geometric Bold uses solid color blocks, no gradients
- `rounded-lg`: Geometric Bold uses sharp corners (rounded-none) or full circles (rounded-full)
- `opacity-50`: Geometric Bold uses full-opacity bold colors for maximum contrast
- `font-light`: Geometric Bold uses heavy font weights (font-bold, font-black)

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

## [CHECKLIST] Geometric Bold post-generation self check

**Before returning code, verify every token and rule below. Fix any violation before delivering:**

### Token check
- [ ] Button includes: `font-bold uppercase tracking-widest transition-colors duration-200`
- [ ] Card includes: `border-4 border-black bg-white`
- [ ] Input includes: `border-4 border-black bg-white font-medium focus:outline-none focus:bg-yellow-300 transition-colors duration-200`

- [ ] Use regular geometric shapes circle, square, triangle
- [ ] Boldly use oversized typography text-6xl, text-8xl, text-[10rem]
- [ ] Use absolute positioning to create overlapping effects
- [ ] Corners use rounded-none or rounded-full

### Style drift check
