## Overview

Design WCAG AAA, alto contraste 7:1, navegação teclado, screen reader. Inclusivo e ético. Prompt validado para acessibilidade. WCAG 1.0 (1999), evoluindo para AAA (2023). Meta: inclusão universal. Screen readers, keyboard nav, alt text, contraste 7:1+.

- Density: 5/10 — Balanced
- Variance: 4/10 — Moderate
- Motion: 6/10 — Expressive

- **Style:** Inclusive, High-Contrast, Semantic, Keyboard-Friendly
- **Keywords:** High contrast, large text (16px+), keyboard navigation, screen reader friendly, WCAG compliant, focus state, semantic
- **Era:** Universal
- **Light/Dark:** ✓ Full / ✓ Full

## Colors

- Palette derived from style keywords and era context

## Typography

- **Display / Hero:** System UI stack (-apple-system, sans-serif) — Weight 700, tight tracking, used for headline impact
- **Body:** System UI stack (-apple-system, sans-serif) — Weight 400, 16px/1.6 line-height, max 72ch per line
- **UI Labels / Captions:** System UI stack (-apple-system, sans-serif) — 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:** Split-screen (text left, visual right).
- **Feature sections:** Zig-zag alternating text+image rows. 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

Clear focus rings (3-4px), ARIA labels, skip links, responsive design, reduced motion, 44x44px touch targets

- **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: 4px. 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 WCAG AAA verified
- Do 7:1+ contrast checked
- Do Keyboard navigation tested
- Do Screen reader tested
- Do Focus visible 3-4px
- Do Semantic HTML used
- Do Touch targets 44x44px

## 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:
   - Navbar (Logo + Links + CTA)

   - CTA Final
   - Footer completo com redes sociais, política de privacidade, termos de uso, contato e links SEO.
5. Todo o conteúdo textual deve ser em Português Brasileiro (PT-BR).

7. Use tags `<style>` no head para classes personalizadas (especialmente para os efeitos complexos de backdrop-filter e animações) que o Tailwind via CDN não cobrir.
8. Responsividade Total: O layout deve se adaptar perfeitamente a Mobile, Tablet e Desktop (Stack vertical no mobile).
