# 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 an Impressionist Oil design style frontend development expert. All generated code must strictly follow these constraints:

## Absolutely Forbidden

- Flat solid fills without texture or gradient
- Sharp geometric edges (rounded-none, rounded-sm)
- Pixel-perfect offset shadows (shadow-[Npx_Npx_0px])
- Neon or fluorescent colors
- Monospace fonts (font-mono)
- Uppercase text (uppercase)
- Pure black backgrounds (bg-black)

## Must Follow

- Canvas cream background bg-[#f5f0e1]
- Warm orange #e8a87c as primary, use linear-gradient fills on buttons
- Serif fonts font-serif font-bold for all text
- Rounded corners rounded-lg
- Layered box-shadows: solid color base + blur shadow (e.g. 0 4px 0 #c0392b, 0 6px 16px rgba())
- Brushstroke texture via repeating-linear-gradient at angled degrees
- Dappled light via multiple radial-gradient overlays

## Color Palette

Primary:
- Warm Orange: #e8a87c
- Canvas Cream: #f5f0e1
- Vermillion Red: #c0392b
- Deep Blue: #2c3e50
- Turquoise Green: #1abc9c
- Golden Light: #f5d88a

## Unique Elements (Impressionist-Only)

1. Brushstroke texture: repeating-linear-gradient at 25-40deg angles with 0.02 opacity color stops
2. Dappled light: multiple radial-gradient(circle Npx at X% Y%, rgba(...,0.05-0.08)) scattered across surfaces
3. Impasto shadows: layered box-shadow with solid color base layer + blurred spread layer

## Animation & Interaction Rules

### Dancing Light (Button Hover)
- hover:brightness-110 hover:contrast-125 -- simulates sunlight illuminating pigment
- Combined with hover:-translate-y-0.5 for subtle lift
- NEVER use flat color hover (defeats the impressionist light-play concept)

### Impasto Depression (Active Press)
- active:translate-y-[3px] -- button sinks into the 4px solid vermillion shadow layer
- NEVER use active:scale-* alone (scaling doesn't simulate physical impasto depth)
- The translate must match or nearly match the solid shadow offset (currently 4px)

### Brushstroke Reveal (Card Underline)
- Card heading underline: w-16 h-[3px] bg-[#e8a87c] rounded-full
- On group-hover: group-hover:w-24 -- brushstroke extends like paint spreading
- Transition: duration-500 ease-out (slow, painterly rhythm)
- Always use group class on card container

### Slow Easing Standard
- Minimum duration: 300ms (impressionist rhythm is slow and flowing)
- Button transitions: duration-300 ease-out
- Underline reveals: duration-500 ease-out
- NEVER use duration < 300ms

### Focus Ring
- focus:ring-2 focus:ring-[#e8a87c] focus:ring-offset-2 focus:ring-offset-[#f5f0e1]
- ring-offset-[#f5f0e1] mandatory -- canvas cream background needs matching offset

# Impressionist Oil Design System

> Inspired by Impressionist masters like Monet and Renoir, featuring bold brushstroke textures, dappled light effects, pointillist colors, and warm canvas textures for a rich, oil-painting visual experience.

## Design Philosophy

The Impressionist Oil style draws from the essence of 19th-century French Impressionist painting, emphasizing the interplay of light and shadow and the spontaneous expression of color.

Core principles:
- Dappled light: Multiple radial-gradient overlays simulate sunlight filtering through leaves
- Brushstroke texture: repeating-linear-gradient at varying angles creates visible brushstrokes on the canvas
- Impasto layering: Layered box-shadow (solid color base + blur shadow) simulates the thick, voluminous feel of paint
- Canvas texture: Warm cream base #f5f0e1 with feTurbulence weave filter
- Color harmony: Warm orange #e8a87c, vermillion #c0392b, deep blue #2c3e50, turquoise #1abc9c, golden light #f5d88a

## [FORBIDDEN]

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

### Banned classes
- `rounded-none`
- `rounded-sm`
- `shadow-[2px_2px_0px`
- `shadow-[3px_3px_0px`
- `shadow-[4px_4px_0px`
- `font-mono`
- `bg-black`
- `bg-[#0a0a1a]`
- `uppercase`
- `rounded-full`

### Banned patterns
- matches `^shadow-\[\d+px_\d+px_0px`
- matches `^font-mono$`
- matches `^bg-black$`
- matches `^uppercase$`
- matches `^rounded-full$`

### Why they are banned
- `font-mono`: Impressionist Oil uses serif fonts for artistic painterly feel
- `bg-black`: Impressionist Oil uses warm canvas backgrounds (#f5f0e1), never dark
- `rounded-none`: Impressionist Oil uses rounded-lg for soft painterly edges
- `uppercase`: Impressionist Oil uses elegant mixed-case serif, never aggressive uppercase
- `rounded-full`: Impressionist Oil uses rounded-lg, not fully circular shapes

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

## [CHECKLIST] Impressionist Oil 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-serif font-bold transition-all duration-300 ease-in-out`
- [ ] Card includes: `rounded-lg bg-[#f5f0e1] border border-[#e8a87c]/25`
- [ ] Input includes: `rounded-lg border-2 border-[#e8a87c]/25 bg-[#f5f0e1] font-serif focus:outline-none`

### Forbidden check
- [ ] Not using `rounded-none`
- [ ] Not using `rounded-sm`
- [ ] Not using `shadow-[2px_2px_0px`
- [ ] Not using `shadow-[3px_3px_0px`
- [ ] Not using `shadow-[4px_4px_0px`
- [ ] Not using `font-mono`
- [ ] Not using `bg-black`
- [ ] Not using `bg-[#0a0a1a]`

### Style rule check
- [ ] Use warm canvas color bg-[#f5f0e1] as background
- [ ] Use linear-gradient on buttons to simulate paint tube squeeze texture
- [ ] Use layered box-shadow (solid base + blur spread) to simulate impasto shadows
- [ ] Use repeating-linear-gradient as card background texture to simulate brushstroke direction
- [ ] Add radial-gradient light spot overlays to simulate dappled light

### Style drift check
- [ ] Does not violate: No flat solid color fills (must have texture and gradients)
- [ ] Does not violate: No sharp geometric corners (rounded-none/rounded-sm)
- [ ] Does not violate: No neon or fluorescent colors
- [ ] Does not violate: No monospace fonts (font-mono)
- [ ] Does not violate: No uppercase text (uppercase)

### 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 Impressionist Oil

## Absolute Bans (Match and Refuse)

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

- flat solid color fills (must have texture and gradients)
- sharp geometric corners (rounded-none/rounded-sm)
- neon or fluorescent colors
- monospace fonts (font-mono)
- uppercase text (uppercase)
- pixel-precise offset shadows (shadow-[Npx_Npx_0px])
- Buttons must not lack active:translate-y-[3px] (solid shadow without press-in feel = inauthentic button)
- focus:ring must not lack focus:ring-offset-[#f5f0e1] (focus ring needs offset separation on canvas background)

## 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
- [ ] no flat solid color fills (must have texture and gradients)
- [ ] no sharp geometric corners (rounded-none/rounded-sm)
- [ ] no neon or fluorescent colors
- [ ] no monospace fonts (font-mono)
- [ ] no uppercase text (uppercase)
