# 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: Particle System
TYPE: Deep dark tech aesthetic with floating particle network

MUST USE:
- Background: Deep blue-black (#0a0e1a or #0f1419)
- Particles: Small circles (1-6px) in semi-transparent white/blue/teal, slowly drifting
- Connection lines: Thin lines between nearby particles, very low opacity
- Text: Light blue-white (#e0e8ff) for primary, white/50 for secondary
- Cards: Very dark glass (bg-[#0f1419]/80) with minimal borders (white/5)
- Accents: Blue (#3b82f6), Teal (#14b8a6), Violet (#a78bfa)
- Interactive elements: Subtle blue glow on hover
- Backdrop blur on cards and overlays

MUST AVOID:
- Light backgrounds
- Warm or earthy color palettes
- Heavy borders or thick outlines
- Conventional box shadows
- Patterns that compete with particle animation

Animation & Interaction Rules:
- Node Excitation: On hover, use thin border highlights and corner micro-bright spots to express node activation and energy injection.
- Nebula Glow: Shadows use low-opacity wide-spread blue-teal diffusion, avoiding heavy solid shadows.
- Quantum Snap: Foreground control interactions use duration-150~200, maintaining precise fast feedback.
- Text Illumination: On card hover, secondary text can brighten from white/50 to white/70 or bright blue.

# Particle System Design System

> A floating particle network on deep dark tech backgrounds, using connection lines, pulses, and trails to create a sense of data flow. Ideal for tech companies, data visualization, and creative portfolios.

## Design Philosophy

A living network of floating particles and connection lines creates a sense of data flowing through space -- tech-forward yet organic and mesmerizing.

Core principles:
- Deep dark backgrounds provide the canvas for luminous particle effects
- Particles drift slowly and randomly, forming organic constellations
- Connection lines appear between nearby particles at low opacity
- Foreground content stays clean, readable, and unobstructed
- Cool-toned accents (blue, teal, violet) reinforce the tech atmosphere

## [FORBIDDEN]

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

### Banned classes
- `bg-white`
- `bg-gray-50`
- `bg-gray-100`
- `border-black`
- `border-gray-900`
- `shadow-sm`
- `shadow-md`
- `shadow-lg`
- `text-gray-900`
- `text-black`

### Banned patterns
- matches `^bg-white`
- matches `^bg-gray-[1-3]00`
- matches `^shadow-(sm|md|lg|xl)$`
- matches `^text-gray-[8-9]00`
- matches `^text-black`

### Why they are banned
- `bg-white`: Particle system uses deep dark backgrounds only
- `bg-gray-50`: Light backgrounds break the particle aesthetic
- `shadow-sm`: Use glow effects (shadow-[...]) instead of conventional shadows
- `text-gray-900`: Use light text (#e0e8ff or white/50) on dark backgrounds
- `text-black`: Dark text is unreadable on dark particle backgrounds

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

## [CHECKLIST] Particle System post-generation self check

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

### Token check
- [ ] Button includes: `rounded-lg font-medium transition-all duration-300`
- [ ] Card includes: `backdrop-blur rounded-xl border border-white/5`
- [ ] Input includes: `bg-[#0a0e1a] border border-white/10 rounded-lg text-[#e0e8ff] focus:border-blue-500/50`

### Forbidden check
- [ ] Not using `bg-white`
- [ ] Not using `bg-gray-50`
- [ ] Not using `bg-gray-100`
- [ ] Not using `border-black`
- [ ] Not using `border-gray-900`
- [ ] Not using `shadow-sm`
- [ ] Not using `shadow-md`
- [ ] Not using `shadow-lg`

### Style rule check
- [ ] Use deep dark backgrounds (blue-black #0a0e1a or #0f1419)
- [ ] Add floating particle elements as background decoration
- [ ] Show connection lines between nearby particles at low opacity
- [ ] Keep foreground content clean and highly readable
- [ ] Use cool-toned accent colors (blue, teal, violet)

### Style drift check
- [ ] Does not violate: Don't let particles obscure content readability
- [ ] Does not violate: Don't use warm or earthy colors for primary palette
- [ ] Does not violate: Don't use heavy borders or thick outlines
- [ ] Does not violate: Don't use patterns that compete with particle animation
- [ ] Does not violate: Don't use light backgrounds

### Delivery check
- [ ] Responsive layout holds on phone, tablet and desktop with no horizontal overflow
- [ ] Every interactive element has a visible focus state, an accessible name and a reduced-motion path
- [ ] Text contrast meets WCAG AA and colour alone never carries state
- [ ] The result is still recognizable at a glance as Particle System

## Absolute Bans (Match and Refuse)

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

- let particles obscure content readability
- use warm or earthy colors for primary palette
- use heavy borders or thick outlines
- use patterns that compete with particle animation
- use light backgrounds
- use conventional box shadows (use glow effects instead)
- let hover glow become solid opaque blocks (must stay airy and translucent)
- apply long bouncy easing to controls (particle UI should feel precise)

## Self-Check (Verify Before Shipping)

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

- [ ] No purple-to-blue gradients
- [ ] No overused fonts (Inter, Roboto, Geist, Fraunces, Plus Jakarta Sans)
- [ ] No nested cards (cards inside cards)
- [ ] No gray text on colored backgrounds
- [ ] Body text contrast meets WCAG AA (>= 4.5:1)
- [ ] No bounce or elastic easing curves
- [ ] Animations have a prefers-reduced-motion fallback
- [ ] Body text line length capped at 65-75 characters
- [ ] No side-stripe accent borders (border-left/right > 1px)
- [ ] No gradient text (background-clip: text)
- [ ] No glassmorphism used as the default surface treatment
- [ ] No tiny uppercase tracked eyebrow labels above every section heading
- [ ] don't let particles obscure content readability
- [ ] don't use warm or earthy colors for primary palette
- [ ] don't use heavy borders or thick outlines
- [ ] don't use patterns that compete with particle animation
- [ ] don't use light backgrounds
