## Overview

Developer-focused, hacker aesthetic landing page. Ideal for portfolios de desenvolvedores, ferramentas cli, plataformas devops, technical documentation. AI-ready template. Terminal green isn't nostalgia — it's a lineage. The phosphor glow of CRT monitors in the 1970s and 80s wasn't a design choice; it was a constraint of P1 phosphor technology. Green on black persisted because it was cheap, readable, and burned itself into the collective memory of anyone who touched a mainframe. When Hollywood needed shorthand for "computer," they reached for cascading green characters. The Matrix didn't invent the aesthetic — it canonized what every sysadmin already knew viscerally.

The color carries meaning that no amount of rebranding can strip away. Green text on dark backgrounds signals competence, access, and a certain disregard for polish in favor of function. It's the visual language of people who prefer stderr over modal dialogs. Every hacker movie, every CTF competition, every SSH session reinforces the same semiotic contract: if you're reading green monospace, you're closer to the metal than most people will ever get.

Today the aesthetic lives in dev tools, security dashboards, and CLI-first products that wear their technical roots openly. It's not retro — it's a deliberate rejection of the rounded-corner, pastel-gradient mainstream. It says: this tool was built by engineers, for engineers, and it doesn't apologize for that.

- **Cards:** Rounded (6px) 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 white (#FFFFFF) backgrounds — use off-white or dark surfaces
- 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

## Visual Effects

## AI Visual Direction

Design a developer-focused, hacker aesthetic landing page. Use GitHub dark background (#0d1117) with terminal green (#39d353) as primary accent. JetBrains Mono as the ONLY font (monospace throughout). Add scan lines overlay using CSS. Include blinking cursor animation. Style code blocks with syntax coloring. Terminal-style borders and UI elements. Everything should feel like a CLI/terminal interface.

## CSS Technical

```css
font-family: 'JetBrains Mono', monospace, background: #0d1117, color: #e6edf3, .scan-lines { background: repeating-linear-gradient(0deg, transparent, transparent 2px, rgba(0,0,0,0.1) 2px, rgba(0,0,0,0.1) 4px) }, .cursor-blink { animation: blink 1s step-end infinite }, @keyframes blink { 50% { opacity: 0 } }, .terminal-border { border: 1px solid #30363d }, .green-accent { color: #39d353 }, pre code { background: #161b22; padding: 16px; border-radius: 6px }
```

## Design System Variables

```css
--bg-primary: #0d1117, --accent-green: #39d353, --text-primary: #e6edf3, --text-muted: #8b949e, --border-color: #30363d, --code-bg: #161b22, --font-mono: 'JetBrains Mono', --scan-line-gap: 4px, --cursor-speed: 1s

## Implementation Checklist

- ☐ JetBrains Mono como única fonte
- ☐ GitHub dark background #0d1117
- ☐ Terminal green #39d353 como accent
- ☐ Scan lines overlay
- ☐ Blinking cursor animation
- ☐ Code syntax styling
- ☐ Terminal-style borders
- ☐ Responsivo mobile/tablet/desktop

## 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.
