Design System: 3x3 Grid Design

1. Visual Theme & Atmosphere

Estilo Grid 3x3 com layout modular organizado em nove caixas uniformes. Ideal para feeds de Instagram, moodboards, portfólios e design de boutiques. O design em grade 3x3 é fundamentado em sistemas de grid rígidos, popularizado por feeds de Instagram e moodboards digitais. Organiza conteúdo visual de forma modular e equilibrada.

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

2. Color Palette & Roles

Pure White (#FFFFFF) — Light surface, card backgrounds
Soft Grey (#F5F5F5) — Secondary text, borders, muted elements
Charcoal (#333333) — Dark surface, primary background
Accent Blue (#2563EB) — Primary accent, CTAs and interactive elements
Light Grey (#E5E5E5) — Secondary text, borders, muted elements
Medium Grey (#9CA3AF) — Secondary text, borders, muted elements
Dark Grey (#1F2937) — Deep contrast surface
Accent Coral (#FF6B6B) — Primary accent, CTAs and interactive elements

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: Rounded (8px) 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 (8px) 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

Prompt para AI
