Design System: IBM Carbon Enterprise

1. Visual Theme & Atmosphere

Design an IBM Carbon-inspired enterprise landing page. Ideal for enterprise, infraestrutura cloud, plataformas corporativas, consultoria tech. AI-ready template.

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

2. Color Palette & Roles

• Azul IBM (#0f62fe) — Accent highlight, links and focus states
• Branco (#ffffff) — Light surface, card backgrounds
• Gray 100 (#161616) — Secondary text, borders, muted elements
• Gray 10 (#f4f4f4) — Secondary text, borders, muted elements
• Gray 70 (#525252) — Secondary text, borders, muted elements
• Gray 30 (#c6c6c6) — Secondary text, borders, muted elements
• Azul Hover (#0043ce) — Secondary accent
• Vermelho (#da1e28) — Error states, destructive actions

3. Typography Rules

• Display / Hero: IBM Plex Sans — Weight 700, tight tracking, used for headline impact
• Body: IBM Plex Sans — Weight 400, 16px/1.6 line-height, max 72ch per line
• UI Labels / Captions: IBM Plex Sans — 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: Sharp edges (0px) 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: Sharp edges (0px) 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 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

Visual Effects

IBM Plex Sans weight 300 (Light) para display — gravitas corporativa com leveza tipográfica. Único acento: IBM Blue 60 (#0f62fe) para tudo interativo. Border-radius 0px em botões primários — retângulos sem suavização. Inputs com bottom-border (não boxed) — padrão Carbon. Profundidade via layering de cor de fundo (branco → gray 10 → gray 20) sem sombras. Grid 2x de 8px com aderência estrita. Token system --cds-* para todas as cores semânticas. Micro letter-spacing (0.16px em 14px, 0.32px em 12px).

AI Visual Direction

Design an IBM Carbon-inspired enterprise landing page. IBM Plex Sans at weight 300 (Light) for display headlines at 60px. Single accent: IBM Blue 60 (#0f62fe) for all interactive elements. 0px border-radius on primary buttons — unapologetically rectangular. Bottom-border inputs (not boxed). Depth through background-color layering (white → #f4f4f4 → #e0e0e0), no shadows. Strict 8px grid. Gray 100 (#161616) for text and dark surfaces. Micro letter-spacing (0.16px at 14px). Three weights: 300 display, 400 body, 600 emphasis.

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.
