Design System: Aurora UI

1. Visual Theme & Atmosphere

Vibrant gradient interface inspired by Northern Lights with mesh gradients, smooth color blends, flowing animations. Ideal for saas premium, creative tools, agência moderna, brand exclusiva. AI-ready template.

Density: 5/10 — Balanced
Variance: 4/10 — Moderate
Motion: 6/10 — Expressive

2. Color Palette & Roles

Electric Blue (#0080FF) — Accent highlight, links and focus states
Magenta (#FF1493) — Decorative accent, highlight elements
Cyan (#00FFFF) — Accent highlight, links and focus states

3. Typography Rules

Display / Hero: System UI stack (-apple-system, sans-serif) — Weight 700, tight tracking, used for headline impact
Body: System UI stack (-apple-system, sans-serif) — Weight 400, 16px/1.6 line-height, max 72ch per line
UI Labels / Captions: System UI stack (-apple-system, sans-serif) — 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: Moderately rounded (0.75rem) 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: Moderately rounded (0.75rem) 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: Spring — stiffness 120, damping 20. Confident, weighted transitions.
Entry animations: Fade + translate-Y (16px → 0) over 480ms ease-out. Staggered cascades for lists: 100ms 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 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

AI Prompt

Create a vibrant gradient interface inspired by Northern Lights with mesh gradients, smooth color blends, flowing animations. Use complementary color pairs (blue-orange, purple-yellow), flowing background gradients, subtle continuous animations (8-12s loops), iridescent effects.
