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

# 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: Soft Utility
MUST USE:
- Deep teal primary actions with pale surfaces and distinct state colors
- Rounded-xl to rounded-2xl controls that preserve information density
- Mobile-first bottom action bars and thumb-reachable primary actions
- Explicit default, focus, success, error, disabled, and loading states
- Status colors paired with text or icons; never communicate meaning by color alone
- Fast, restrained motion that supports task completion
MUST AVOID:
- Low-contrast text for task-critical information
- Turning a tool screen into a decorative card gallery
- Removing boundaries or state feedback in the name of softness
- Bouncy animations that slow down repeated actions
INTERACTION:
- Use 160-240ms transitions and scale-[0.98] on press
- Keep primary controls in a consistent location across screens
- Provide undo or confirmation for destructive actions
COLOR ROLES:
- Surface: #f4f8f6
- Text: #203b40
- Primary: #2d5b63
- Success/support: #a9d8cc
- Notice: #f3c98b
- Secondary states: #e6b7b0 and #b8c9ed

## [COMPARE] Soft Utility wrong vs right
The wrong examples below stand for generic library defaults that were never adapted to this style. Do not read them as visual suggestions.
### Button
[WRONG] **Wrong** (generic component library default, do not copy):
```html
<button class="{GENERIC_LIBRARY_BUTTON_DEFAULT}">
Click me
</button>
```
[CORRECT] **Right** (uses this style's tokens):
```html
<button class="rounded-lg border font-medium inline-flex items-center bg-[#2d5b63] text-white">
Click me
</button>
```
### Card
[WRONG] **Wrong** (generic card, not adapted to this style):
```html
<div class="{GENERIC_LIBRARY_CARD_DEFAULT}">
<h3>{TITLE}</h3>
</div>
```
[CORRECT] **Right** (uses this style's card tokens):
```html
<div class="rounded-lg border bg-white/80 p-5 md:p-6">
<h3 class="font-semibold tracking-tight text-xl md:text-2xl">{TITLE}</h3>
</div>
```
### Input
[WRONG] **Wrong** (generic input, not adapted to this style):
```html
<input class="{GENERIC_LIBRARY_INPUT_DEFAULT}" />
```
[CORRECT] **Right** (uses this style's input tokens):
```html
<input class="rounded-lg border bg-background focus:outline-none" placeholder="{PLACEHOLDER}" />

- [ ] Card includes: `rounded-lg border bg-white/80`
- [ ] Input includes: `rounded-lg border bg-background focus:outline-none`
### Forbidden check

### 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 Soft Utility

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 headingMore prompt libraries: All UI Prompts · Tailwind UI Prompts · Dark Mode UI Prompts
