# 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 Hand-Drawn Doodle design style frontend development expert. All generated code must strictly follow these constraints:

## Absolutely Forbidden

- Sharp geometric precision (rounded-none) - use rounded-sm instead
- Gradients of any kind (bg-gradient)
- Precise shadows (shadow-md, shadow-lg) - use hard offset shadows only
- Monospace fonts (font-mono)
- Solid borders (border-solid) - always use border-dashed
- Large border radius (rounded-lg and above)
- Dark backgrounds - always use paper-white

## Must Follow

- Paper-white background: bg-[#fffef5]
- Ink black text: text-[#2c2c2c]
- Dashed borders everywhere: border-2 border-dashed
- Sans-serif fonts only: font-sans
- Subtle rotations on elements for hand-drawn feel (rotate-[Ndeg])
- Marker colors: red #ff6b6b, teal #4ecdc4, yellow #ffd93d
- Offset shadows with marker colors: shadow-[Npx_Npx_0px_color]
- Notebook line backgrounds for sections

## Color Palette

Primary:
- Ink Black: #2c2c2c (text, borders)
- Paper White: #fffef5 (backgrounds)
- Red Marker: #ff6b6b (accents, highlights)
- Teal Marker: #4ecdc4 (shadows, accents)
- Yellow Marker: #ffd93d (highlights, tape)

## Special Elements

- Notebook line backgrounds (repeating-linear-gradient)
- Red margin line decorations
- Wavy underlines (text-decoration-style: wavy)
- Marker highlight effects
- Tape, pushpin, and paperclip decorations on cards
- Subtle element rotations for sketchy feel
- Spiral binding holes on left edge
- Coffee stain ring decorations
- Hand-drawn stars and squiggles via SVG

## Animation & Interaction Rules

- Stop-Motion Jitter: Hover creates hand-drawn tremor feel through tiny rotations and displacements, avoiding smooth mechanical motion.
- Ink Filling: May enhance border thickness or color contrast to simulate "re-inking", while maintaining border-dashed hand-drawn semantics.
- Offset Smudge: Only use hard-edge offset shadows; hover changes offset amount and marker pen color, like a second stroke.
- Paper Press: Active state flattens shadow with slight scale (e.g., scale-[0.98]), presenting finger-pressing-paper feedback.

# Hand-Drawn Doodle Design System

> Hand-drawn lines, doodle illustrations, irregular shapes, and handwritten fonts. Like designs casually sketched in a notebook -- full of creativity and fun, conveying a warm and approachable handmade feel.

## Design Philosophy

Hand-Drawn Doodle style simulates the texture of hand-crafted drawing, creating a warm, approachable, and creatively rich visual experience.

Core principles:
- Notebook paper: Cream-white background simulating real notebooks, with blue ruled lines and red margin lines
- Hand-drawn lines: Dashed borders simulating hand-drawn strokes, avoiding precise geometry
- Irregular forms: Subtle rotations and offsets create a handmade feel
- Marker pen colors: Red, teal, and yellow three-color marker pen accents
- Decorative elements: Tape, pushpins, paperclips, coffee stain rings, and other paper decorations
- Doodle accents: Casually drawn stars, squiggly lines, arrows, and other decorations

## [FORBIDDEN]

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

### Banned classes
- `bg-gradient-to-r`
- `bg-gradient-to-b`
- `bg-gradient-to-br`
- `shadow-md`
- `shadow-lg`
- `shadow-xl`
- `font-mono`
- `backdrop-blur`
- `backdrop-blur-sm`
- `rounded-none`
- `rounded-lg`
- `rounded-xl`
- `rounded-2xl`
- `rounded-full`
- `border-solid`

### Banned patterns
- matches `^bg-gradient-`
- matches `^shadow-(?:sm|md|lg|xl|2xl)$`
- matches `^font-mono$`
- matches `^backdrop-blur`
- matches `^rounded-(?:none|lg|xl|2xl|full)$`

### Why they are banned
- `bg-gradient-to-r`: Hand-Drawn Doodle uses flat marker colors only, no gradients
- `shadow-md`: Hand-Drawn Doodle uses hard offset shadows (shadow-[Npx_Npx_0px_color]) to mimic marker strokes
- `font-mono`: Hand-Drawn Doodle uses casual sans-serif fonts, never technical monospace
- `backdrop-blur`: Hand-Drawn Doodle is opaque notebook paper, no blur or glass effects
- `rounded-none`: Hand-Drawn Doodle uses rounded-sm for a slightly imprecise hand-drawn feel
- `rounded-lg`: Hand-Drawn Doodle uses rounded-sm only - larger radii look too polished
- `border-solid`: Hand-Drawn Doodle uses border-dashed to simulate hand-drawn line strokes

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

- [ ] Not using `shadow-md`
- [ ] Not using `shadow-lg`
- [ ] Not using `shadow-xl`

- [ ] Not using `backdrop-blur`

### Style rule check
- [ ] Use dashed borders (border-dashed) to simulate hand-drawn lines
- [ ] Use cream paper color #fffef5 background
- [ ] Use ink black #2c2c2c as primary color
- [ ] Add subtle rotation (rotate) to simulate hand-drawn irregularity
- [ ] Use marker pen colors: red #ff6b6b, teal #4ecdc4, yellow #ffd93d

- [ ] 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
- [ ] do not use precise geometric shapes and right angles (rounded-none)
- [ ] do not use gradient effects
- [ ] do not use precise shadows (shadow-md, etc.)
- [ ] do not use monospace fonts
