## Overview

Design system técnico e enterprise inspirado no Helios da HashiCorp. Interface limpa com azul de ação, alta densidade de dados e acessibilidade WCAG AA. Ideal para ferramentas DevOps e SaaS técnico. O Helios é o design system da HashiCorp, criado para unificar produtos como Terraform, Vault e Consul. Prioriza clareza técnica, acessibilidade e densidade de informação para engenheiros.

## Colors

- **Action Blue** (#1060ff) — Accent highlight, links and focus states
- **Foreground Strong** (#0c0c0e) — Secondary surface or text color
- **Surface Primary** (#ffffff) — Primary accent, CTAs and interactive elements

- **UI Labels / Captions:** Segoe UI — 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

Small border-radius (5-6px), layered elevation (soft shadows for interactivity), precise grid layouts, high contrast ratios (WCAG AA), subtle hover transitions

- **Physics:** Ease-out curves, 200-300ms duration. Smooth and predictable.
- **Entry animations:** Fade + translate-Y (16px → 0) over 420ms ease-out. Staggered cascades for lists: 80ms between items.
- **Hover states:** Subtle color shift + shadow adjustment over 200ms.
- **Page transitions:** Fade only (200ms).
- **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 Action Blue #1060ff
- Do Border-radius 5-6px
- Do System font stack
- Do Data-dense layout spacing
- Do High contrast accessibility (WCAG AA)

## Direção Visual para IA

Create a highly structured and technical enterprise UI inspired by HashiCorp Helios. Use a clean white surface with high-contrast dark text. Incorporate a primary blue (#1060ff) for actions. Components should have small rounded corners (5-6px) and very subtle shadows. Focus on data density, clear hierarchy, and technical precision. Use system fonts (SF Pro, Segoe UI).

## 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)
   - Hero Section (Headline impactante + Subtitle + 2 botões + Elemento visual 3D/Abstrato via CSS)
