Design System: Bold Signal

1. Visual Theme & Atmosphere

Bold, confident dark landing page. Ideal for creative agencies, startups tech, portfolios de design, apresentações corporativas. AI-ready template.

• Density: 5/10 — Balanced
• Variance: 2/10 — Structured
• Motion: 4/10 — Subtle

2. Color Palette & Roles

• Dark Background (#1a1a1a) — Primary background surface
• Card Orange (#FF5722) — Warm accent, call-to-action secondary
• White (#FFFFFF) — Light surface, card backgrounds
• Dark Gradient (#2d2d2d) — Deep contrast surface
• Text on Card (#1a1a1a) — Primary text color
• Muted Grey (#888888) — Secondary text, borders, muted elements

3. Typography Rules

• Display / Hero: Archivo Black — Weight 700, tight tracking, used for headline impact
• Accent: Space Grotesk — Used for decorative or emphasis text
• Body: Archivo Black — Weight 400, 16px/1.6 line-height, max 72ch per line
• UI Labels / Captions: Archivo Black — 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

4. Component Stylings

• 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.

5. Layout Principles

• 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).

6. Motion & Interaction

• 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.

7. Anti-Patterns (Banned)

• 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

AI Visual Direction

Design a bold, confident dark landing page. Use a colored card (orange/coral) as the focal point on a dark gradient background. Add large section numbers (01, 02, 03) top-left. Include navigation breadcrumbs with active/inactive opacity states. Use Archivo Black for display and Space Grotesk for body. Grid-based layout with precise alignment.

CSS Technical

background: linear-gradient(135deg, #1a1a1a 0%, #2d2d2d 50%, #1a1a1a 100%), font-family: 'Archivo Black' for headings, 'Space Grotesk' for body, color: #FFFFFF, .card-accent { background: #FF5722; color: #1a1a1a }, .section-number { font-size: 6rem; font-weight: 900; opacity: 0.15 }

Design System Variables

--bg-primary: #1a1a1a, --bg-gradient: linear-gradient(135deg, #1a1a1a 0%, #2d2d2d 50%, #1a1a1a 100%), --card-bg: #FF5722, --text-primary: #ffffff, --text-on-card: #1a1a1a, --font-display: 'Archivo Black', --font-body: 'Space Grotesk', --section-number-size: 6rem

Implementation Checklist

• ☐ Archivo Black + Space Grotesk carregados
• ☐ Dark gradient background
• ☐ Colored card focal point (#FF5722)
• ☐ Large section numbers (01
• 02
• ☐ Navigation breadcrumbs com opacity
• ☐ Grid-based layout preciso
• ☐ 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.
