# 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 frontend expert specializing in Fullscreen Hero layout. All generated code must strictly follow these constraints:

## Absolute Prohibitions

- Do NOT place text on busy backgrounds without overlay
- Do NOT use low-quality or stretched images
- Do NOT ignore mobile responsiveness
- Do NOT fill entire viewport with no breathing room
- Do NOT autoplay video with sound

## Must Follow

- Container: min-h-screen or h-screen
- Background: object-cover for images
- Overlay: gradient or solid for text readability
- Content: centered with max-width constraint
- Scroll indicator: at bottom of hero
- Navigation: absolute positioned, transparent

## Structure

Layers (bottom to top):
1. Background image/video (absolute, full cover)
2. Overlay (gradient or solid color)
3. Content (relative z-10, centered)
4. Navigation (absolute top)
5. Scroll indicator (absolute bottom)

## Background Options

Image:
- object-fit: cover
- Full viewport coverage
- High quality, relevant imagery

Video:
- Muted, autoplay, loop
- Fallback poster image
- Pause on mobile (optional)

Overlay types:
- Solid: bg-black/50
- Gradient: from-black/80 via-transparent to-black/30
- Color: bg-brand/70 mix-blend-multiply

## Content

- Badge/label (optional)
- Main headline (large, bold)
- Subheadline (medium)
- CTA buttons (prominent)
- Max-width container (4xl recommended)

## Responsive

Mobile:
- Smaller text sizes
- Stacked CTA buttons
- Simpler background (may hide video)

Desktop:
- Full visual impact
- Side-by-side buttons
- All animations enabled

## Animation & Interaction Rules

### Gravity Focus (CTA Button)
- Resting: shadow-[0_4px_14px_rgba(0,0,0,0.3)]
- Hover: hover:-translate-y-1 hover:shadow-[0_8px_28px_rgba(0,0,0,0.5)] -- gravity float with shadow burst
- Active: active:scale-[0.98] active:translate-y-0 active:shadow-[0_2px_8px_rgba(0,0,0,0.3)] -- tactile press
- Focus: focus:ring-2 focus:ring-white/80 focus:ring-offset-2 focus:ring-offset-black/50

### Floating Glass (Feature Cards)
- Always use group class on card container
- Hover: hover:-translate-y-2 hover:shadow-[0_16px_40px_rgba(0,0,0,0.5)] -- dramatic float
- Icon container: group-hover:scale-110 transition-transform duration-300 ease-out

### Text Reveal on Hover
- h3: group-hover:text-white/95 transition-colors duration-200
- p: group-hover:text-white/85 transition-colors duration-200

### Tactile Confirmation
- All buttons: active:scale-[0.98] -- required for perceived responsiveness on dark overlay
- Duration: 200ms ease-out for all interactive elements

## Self-Check

After generating code, verify:
1. Hero is full viewport height
2. Text is readable on background
3. Overlay provides contrast
4. Scroll indicator visible
5. Mobile layout works

## [FORBIDDEN]

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

### Banned classes
- `shadow-sm`
- `shadow-md`
- `shadow-lg`
- `shadow-xl`
- `bg-zinc-50`
- `bg-gray-50`
- `text-zinc-900`
- `text-gray-900`

### Banned patterns
- matches `^shadow-(?!none)`
- matches `^bg-(?:zinc|gray)-(?:50|100)`
- matches `^border-(?:zinc|gray)-`

### Why they are banned
- `shadow-lg`: Hero Fullscreen uses overlays and contrast instead of shadows

- `text-black`: Hero Fullscreen uses white text on dark overlaid backgrounds

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

## [CHECKLIST] Fullscreen Hero post-generation self check

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

### Token check
- [ ] Button includes: `px-8 py-4 font-semibold text-lg rounded-full transition-colors`
- [ ] Card includes: `bg-white/10 backdrop-blur-sm rounded-2xl border border-white/20`
- [ ] Input includes: `bg-white/10 backdrop-blur-sm border border-white/30 rounded-full text-white placeholder-white/60 focus:outline-none focus:ring-2 focus:ring-white/50`

### Forbidden check
- [ ] Not using `shadow-sm`
- [ ] Not using `shadow-md`
- [ ] Not using `shadow-lg`
- [ ] Not using `shadow-xl`
- [ ] Not using `bg-zinc-50`
- [ ] Not using `bg-gray-50`
- [ ] Not using `text-zinc-900`
- [ ] Not using `text-gray-900`

### Style rule check
- [ ] Use h-screen or min-h-screen to ensure fullscreen coverage
- [ ] Use object-cover on images to maintain aspect ratio fill
- [ ] Add gradient or semi-transparent overlays to ensure text readability
- [ ] Position content absolutely or center with flex
- [ ] Provide scroll indicators to guide users downward

### Style drift check
- [ ] Does not violate: Do NOT place text directly on complex backgrounds without an overlay
- [ ] Does not violate: Do NOT use low-quality or stretched images
- [ ] Does not violate: Do NOT ignore mobile responsiveness
- [ ] Does not violate: Do NOT fill the entire space with content and no whitespace
- [ ] Does not violate: Do NOT autoplay video with sound

### 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 Fullscreen Hero

2. Dark gradient overlay for text contrast
3. Badge: "Announcing [Product Name]"
4. Large headline with gradient text highlight
5. Subheadline describing key benefit
6. Two CTAs: "Pre-order Now" and "Learn More"
7. Scroll indicator at bottom

Modern, tech-forward aesthetic
```

```
Create an event promotion fullscreen hero:
1. Event venue/crowd image as background

## Absolute Bans (Match and Refuse)

- place text directly on complex backgrounds without an overlay
- use low-quality or stretched images
- ignore mobile responsiveness
- fill the entire space with content and no whitespace
- autoplay video with sound
- omit active:scale-[0.98] on buttons (buttons without tactile confirmation feel terrible on fullscreen backgrounds)
- omit group class on cards (icon group-hover:scale-110 micro-interaction depends on group)
