Design System: Shabby Chic

1. Visual Theme & Atmosphere

Estilo Shabby Chic com tons pastel desbotados, florais vintage e romance rústico. Ideal para convites de casamento, embalagens acolhedoras e marcas nostálgicas. O Shabby Chic surgiu nos anos 80-90 na Inglaterra, celebrando a beleza do desgaste e do reaproveitamento. Combina romance vintage com rusticidade acolhedora em tons pastel desbotados.

• Density: 5/10 — Balanced
• Variance: 7/10 — Dynamic
• Motion: 4/10 — Subtle

2. Color Palette & Roles

• Faded Rose (#E8C4C4) — Primary surface or dominant color
• Antique White (#FAF0E6) — Light surface, card backgrounds
• Soft Sage (#C5D5C5) — Supporting palette color
• Dusty Blue (#A4B8C4) — Accent highlight, links and focus states
• Lavender Mist (#D8D0E0) — Extended palette, decorative use
• Warm Linen (#F0E6D6) — Extended palette, decorative use
• Blush Pink (#F5D5D5) — Primary text color
• Weathered Wood (#B8A898) — Error states, destructive actions

3. Typography Rules

• Display / Hero: Lora — Weight 700, tight tracking, used for headline impact
• Body: Lora — Weight 400, 16px/1.6 line-height, max 72ch per line
• UI Labels / Captions: Lora — 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: Rounded (6px) 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: 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.

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: 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
