Design System: Synthwave

1. Visual Theme & Atmosphere

Estilo Synthwave com gradientes de pôr do sol, grades neon e estética retro-futurista dos anos 80. Ideal para capas de álbuns, promoções de marca e visuais neon. O Synthwave revive a estética retro-futurista dos anos 80, inspirado por arcades, música eletrônica e filmes como Blade Runner. Grades neon, palmeiras e pôr do sol cromado definem o estilo.

• Density: 5/10 — Balanced
• Variance: 7/10 — Dynamic
• Motion: 8/10 — Cinematic

2. Color Palette & Roles

• Sunset Orange (#FF6B35) — Warm accent, call-to-action secondary
• Neon Pink (#FF1493) — Primary text color
• Deep Purple (#2D1B69) — Accent color, emphasis elements
• Horizon Blue (#1B1464) — Accent highlight, links and focus states
• Neon Cyan (#00FFFF) — Secondary accent
• Chrome Silver (#C0C0C0) — Extended palette, decorative use
• Hot Magenta (#FF00FF) — Decorative accent, highlight elements
• Dark Navy (#0A0A2E) — Deep contrast surface

3. Typography Rules

• Display / Hero: Orbitron — Weight 700, tight tracking, used for headline impact
• Body: Orbitron — Weight 400, 16px/1.6 line-height, max 72ch per line
• UI Labels / Captions: Orbitron — 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: Asymmetric composition.
• Feature sections: Asymmetric grid with varied card sizes. 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: Spring — stiffness 120, damping 20. Confident, weighted transitions.
• Entry animations: Fade + translate-Y (16px → 0) over 540ms ease-out. Staggered cascades for lists: 120ms 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.

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
