## Overview

Doodle art landing page with hand-drawn, sketch-like aesthetics. Ideal for branding lúdico, creative agencies, produtos para público jovem, editoriais divertidos. AI-ready template. The doodle is older than graphic design itself. Marginalia in medieval manuscripts, Leonardo's notebook sketches, Saul Steinberg's deceptively simple line work for The New Yorker — the conceptual sketch has always been the thinking person's visual language. It's not decoration; it's cognition made visible. The hand-drawn line carries something a vector never will: the tremor of an idea still forming.

In the 1960s and 70s, designers like Corita Kent and Sister Mary Corita proved that raw, unpolished mark-making could carry enormous conceptual weight. Later, Stefan Sagmeister's hand-scrawled typography and Christoph Niemann's abstract Sunday Sketches demonstrated that the doodle wasn't primitive — it was deliberately unfinished, inviting the viewer to complete the thought. Today, tools like Excalidraw and FigJam have digitized the aesthetic, but the best implementations still honor the original premise: a sketch is a conversation, not a deliverable.

## Elevation & Depth

Hand-drawn SVG borders (wavy/irregular), sketch-style underlines, notebook paper background (lined or grid), doodle arrow decorations, wiggle animations on hover, pencil texture overlays

- **Physics:** Spring — stiffness 120, damping 20. Confident, weighted transitions.
- **Entry animations:** Fade + translate-Y (16px → 0) over 480ms ease-out. Staggered cascades for lists: 100ms between items.
- **Hover states:** Scale(1.03) + shadow lift over 200ms.
- **Page transitions:** Fade + slide (300ms).
- **Performance:** Only transform and opacity animated. No layout-triggering properties.


## Shapes

Base corner radius: 0px. See rounded tokens in front matter for the full scale.


## Components

- **Navigation:** Primary surface background. Active item: accent color indicator. Font weight 500 when active.
- **Skeletons:** Shimmer animation matching component dimensions. No circular spinners.
- **Empty States:** Icon-based composition with descriptive text and action button.


## Do's and Don'ts

- No pure black (#000000) — use off-black or charcoal variants
- No oversaturated accent colors (saturation cap: 80%)
- No 3-column equal-width feature layouts — use zig-zag or asymmetric grid
- No `h-screen` — use `min-h-[100dvh]`
- No AI copywriting clichés: "Elevate", "Seamless", "Unleash", "Next-Gen"
- No broken external image links — use picsum.photos or inline SVG
- No generic lorem ipsum in demos

- Do Hand-drawn style borders (wavy SVG)
- Do Notebook paper background
- Do Handwritten font family
- Do Doodle decorative elements
- Do Slight rotation on elements for sketch feel

## Visual Effects

Hand-drawn SVG borders (wavy/irregular), sketch-style underlines, notebook paper background (lined or grid), doodle arrow decorations, wiggle animations on hover, pencil texture overlays

## AI Visual Direction

Design a doodle art landing page with hand-drawn, sketch-like aesthetics. Use notebook paper backgrounds (lined or grid), wavy irregular SVG borders, pencil-grey and ink-black with colorful marker accents. Typography should look handwritten (Caveat, Patrick Hand). Include doodle arrows, scribble decorations, and wiggle animations. Playful, spontaneous and creative atmosphere.

## CSS Technical

```css
font-family: 'Caveat', cursive, background: #FAFAF5 with CSS grid lines, color: #1A1A1A, border: 2px solid #4A4A4A with SVG wavy filter, box-shadow: none, transform: rotate(-1deg to 1deg) for hand-drawn feel, animation: wiggle 0.3s on hover
```

## Design System Variables

```css
--color-paper: #FAFAF5, --color-pencil: #4A4A4A, --color-ink: #1A1A1A, --font-handwritten: 'Caveat', --border-sketch: 2px solid #4A4A4A, --rotation-range: -1deg to 1deg, --spacing: 1.5rem, --border-radius: 0px
```

## Implementation Checklist

- ☐ Hand-drawn style borders (wavy SVG)
- ☐ Notebook paper background
- ☐ Handwritten font family
- ☐ Doodle decorative elements
- ☐ Slight rotation on elements for sketch feel
- ☐ Colorful marker accent colors
- ☐ Responsive with maintained sketch aesthetic

## Execution Rules

1. Strictly follow the defined visual style.
2. Use high-quality inline SVG icons (Heroicons or Lucide style) — NEVER use emojis as icons.
3. Add `cursor-pointer` and smooth `hover` states (transition-all) on all interactive elements.
4. Required Page Structure:
   - Navbar (Logo + Links + CTA)
   - Hero Section (Impactful Headline + Subtitle + 2 buttons + 3D/Abstract visual element via CSS)
   - Features (3 cards with icons)
   - Testimonials (3 cards)
   - Pricing (3 tiers, highlight the middle one)
   - Final CTA
   - Full Footer with social links, privacy policy, terms of use, contact and SEO links.
5. All text content must be in English.
6. The visual must be CLEARLY distinct — do not create a "default Bootstrap" design. Force the use of the provided design system variables.
7. Use `<style>` tags in the head for custom classes (especially for complex backdrop-filter effects and animations) that Tailwind CDN doesn't cover.
8. Full Responsiveness: Layout must adapt perfectly to Mobile, Tablet and Desktop (vertical stack on mobile).
9. Include basic SEO, Viewport and Open Graph meta tags in `<head>`.
10. Footer must contain: Copyright 2026, Secondary navigation links and Social media icons.
11. Make the creative decisions needed to deliver the complete, functional result now.
