## Colors

- **Marker Black** (#2C2C2C) — Dark surface, primary background
- **Marker Blue** (#1565C0) — Accent highlight, links and focus states
- **Marker Red** (#D32F2F) — Error states, destructive actions

## Typography

- **Display / Hero:** Architects Daughter — Weight 700, tight tracking, used for headline impact
- **Accent:** Patrick Hand — Used for decorative or emphasis text
- **Body:** Architects Daughter — Weight 400, 16px/1.6 line-height, max 72ch per line
- **UI Labels / Captions:** Architects Daughter — 0.875rem, weight 500, slight letter-spacing
- **Monospace:** JetBrains Mono — Used for code, metadata, and technical values

Scale:
- Hero: clamp(2.5rem, 5vw, 4rem)
- H1: 2.25rem
- H2: 1.5rem
- Body: 1rem / 1.6
- Small: 0.875rem

## Layout

- **Grid:** CSS Grid primary. Max-width containment: 1280px centered with 1.5rem side padding.
- **Spacing rhythm:** Balanced. Base unit: 0.5rem (8px).
- **Section vertical gaps:** clamp(4rem, 8vw, 8rem).
- **Hero layout:** Asymmetric composition.
- **Feature sections:** Asymmetric grid with varied card sizes. No 3-equal-columns.
- **Mobile collapse:** All multi-column layouts collapse below 768px. No horizontal overflow.
- **z-index contract:** base (0) / sticky-nav (100) / overlay (200) / modal (300) / toast (500).

## Elevation & Depth

Hand-drawn style borders (slightly irregular via SVG filter), marker-weight typography (variable stroke), subtle grid/dot pattern background, sticky note elements with slight rotation (1-3deg), connector lines between sections, whiteboard shadow on edges

- **Physics:** Spring — stiffness 120, damping 20. Confident, weighted transitions.
- **Entry animations:** Fade + translate-Y (16px → 0) over 540ms ease-out. Staggered cascades for lists: 120ms 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: 8px. See rounded tokens in front matter for the full scale.

## Components

- **Primary Button:** Subtly rounded (0.5rem) shape. Accent color fill. Hover: 8% darken + subtle lift shadow. Active: -1px translate tactile press. Font weight 600. No outer glows.
- **Secondary / Ghost Button:** Outline variant. 1.5px border in muted color. Text in primary color. Hover: subtle background fill.
- **Cards:** Subtly rounded (0.5rem) corners. Surface background. Subtle shadow (0 2px 12px rgba(0,0,0,0.06)). 1px border stroke.
- **Inputs:** Label above input. 1px border stroke. Focus ring: 2px accent color offset 2px. Error text below in semantic red. No floating labels.
- **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 emojis in UI — use icon system only (Lucide, Heroicons)
- 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 Clean white background with dot grid
- Do Marker-style colored typography
- Do Sticky note elements with rotation
- Do Hand-drawn style borders
- Do Connector lines between sections
- Do Sketch-style SVG icons

Use marker-style typography in black, blue, red, and green. Include sticky note elements with slight rotation, hand-drawn connector lines, and sketch-style icons. Cards should look like pinned notes. Add whiteboard marker thickness variation in borders.

background: #FEFEFE with radial-gradient dot pattern, border: 2px solid with slight irregularity via SVG filter, font-family: 'Architects Daughter' or 'Patrick Hand', transform: rotate(1-3deg) for sticky notes, box-shadow: 2px 2px 5px rgba(0,0,0,0.1) for pinned effect, background-color: #FFF9C4 for highlight areas
```

## Regras de Execução

1. Siga fielmente o estilo visual determinado.
2. Use ícones SVG inline de alta qualidade (estilo Heroicons ou Lucide) — PROIBIDO usar emojis como ícones.
3. Adicione `cursor-pointer` e estados de `hover` suaves (transition-all) em todos os elementos interativos.
4. Estrutura Obrigatória da Página:
