Design Luxury

Luxury Design System (K3 Blueprint)

Architect: K3 Ecosystem (bergside inspired) Target: Next.js 15 + Tailwind v4 + Shadcn UI

Mission

Execute a high-end, dramatic, expensive-feeling dark UI. Implement strict high-contrast text on true #000000 backgrounds.

1. Next.js Font Implantation

Inject these exact font definitions into app/layout.tsx:

import { Oswald, Inter, JetBrains_Mono } from 'next/font/google';

const oswald = Oswald({ subsets: ['latin'], variable: '--font-heading' });
const inter = Inter({ subsets: ['latin'], variable: '--font-sans' });
const jetbrainsMono = JetBrains_Mono({ subsets: ['latin'], variable: '--font-mono' });

// Add to body className: `${oswald.variable} ${inter.variable} ${jetbrainsMono.variable} font-sans antialiased`

2. Tailwind v4 @theme Overrides (globals.css)

Inject these absolute value mappings to force Shadcn into the Luxury paradigm.

@theme inline {
  --color-background: #000000;
  --color-foreground: #FAFAFA;
  
  --color-primary: #FAFAFA;
  --color-primary-foreground: #000000;
  
  --color-secondary: #111111;
  --color-secondary-foreground: #E4E4E7;
  
  --color-muted: #111111;
  --color-muted-foreground: #A1A1AA;
  
  --color-accent: #222222;
  --color-accent-foreground: #FAFAFA;
  
  --color-border: #222222;
  --color-input: #222222;
  --color-ring: #FAFAFA;
  
  --font-sans: var(--font-sans), ui-sans-serif, system-ui;
  --font-heading: var(--font-heading), ui-sans-serif, system-ui;
  --font-mono: var(--font-mono), ui-monospace, SFMono-Regular;
  
  --radius-lg: 0px; /* Luxury favors sharp precision */
  --radius-md: 0px;
  --radius-sm: 0px;
}

3. UI Implementation Mandates

• Buttons: Use sharp corners (radius 0). The primary action button must be solid white (bg-primary text-primary-foreground).
• Headings: Must use the font-heading explicitly (e.g., className="font-heading text-4xl uppercase tracking-widest").
• Whitespace: Demand immense padding around structural elements.
• Borders: Keep to an absolute minimum. Rely on spatial separation. If borders are used, they must be subtle (border-border, which maps to #222222).
