Customizing Components

Components live in web/src/@/components/ui/ - modify them directly:

tsx

// web/src/@/components/ui/button.tsx - you own this!
const buttonVariants = cva(
  "inline-flex items-center justify-center rounded-md text-sm font-medium...",
  {
    variants: {
      variant: {
        default: "bg-primary text-primary-foreground hover:bg-primary/90",
        // Add your own variants:
        accent: "bg-accent text-accent-foreground shadow-lg shadow-accent/25",
        glow: "bg-accent text-accent-foreground shadow-lg shadow-accent/30 hover:shadow-xl hover:shadow-accent/40",
      },
      size: {
        default: "h-10 px-4 py-2",
        sm: "h-9 rounded-md px-3",
        lg: "h-11 rounded-md px-8",
        // Add custom sizes:
        xl: "h-14 rounded-lg px-10 text-lg font-semibold",
      },
    },
  }
);

Theming with CSS Variables

shadcn/ui uses CSS variables for theming. Define in globals.css:

css

@layer base {
  :root {
    --background: 0 0% 100%;
    --foreground: 222.2 84% 4.9%;
    --card: 0 0% 100%;
    --card-foreground: 222.2 84% 4.9%;
    --popover: 0 0% 100%;
    --popover-foreground: 222.2 84% 4.9%;
    --primary: 222.2 47.4% 11.2%;
    --primary-foreground: 210 40% 98%;
    --secondary: 210 40% 96%;
    --secondary-foreground: 222.2 47.4% 11.2%;
    --muted: 210 40% 96%;
    --muted-foreground: 215.4 16.3% 46.9%;
    --accent: 142 76% 36%; /* Your signature color */
    --accent-foreground: 0 0% 100%;
    --destructive: 0 84.2% 60.2%;
    --destructive-foreground: 210 40% 98%;
    --border: 214.3 31.8% 91.4%;
    --input: 214.3 31.8% 91.4%;
    --ring: 222.2 84% 4.9%;
    --radius: 0.5rem;
  }

  .dark {
    --background: 222.2 84% 4.9%;
    --foreground: 210 40% 98%;
    /* ... dark mode overrides */
  }
}

Dark Mode (next-themes)

Already configured in the project:

tsx

// Toggle theme
import { useTheme } from "next-themes";

const { theme, setTheme } = useTheme();
setTheme("dark"); // or "light" or "system"

Design Thinking Process

Before coding, commit to a BOLD aesthetic direction:

1. Purpose

What problem does this interface solve? Who uses it?

2. Tone - Pick an Extreme

Choose ONE and execute with precision:

Aesthetic	Description	When to Use
Brutally minimal	Stark, lots of whitespace, dramatic typography	Landing pages, statements
Data-dense terminal	Monospace, dark mode, information-rich	Dashboards, analytics
Luxury financial	Bloomberg-inspired, sophisticated, precise	Professional tools
Editorial/magazine	Large type, asymmetric layouts, photography	Content, about pages
Retro-futuristic	Neon accents, gradients, sci-fi vibes	Creative, experimental
Art deco/geometric	Gold accents, patterns, elegant shapes	Premium features

3. Differentiation

What makes this UNFORGETTABLE? What's the one thing someone will remember?

CRITICAL: Choose a clear conceptual direction and execute with precision. Bold maximalism and refined minimalism both work - the key is intentionality.

Typography with Tailwind

AVOID Generic Fonts (AI Slop)

tsx

// ❌ NEVER - These scream "AI generated"
className = "font-sans"; // Inter, system fonts
className = "font-inter"; // Overused
className = "font-roboto"; // Generic

USE Distinctive Fonts

Configure in tailwind.config.ts:

typescript

// tailwind.config.ts
import { fontFamily } from "tailwindcss/defaultTheme";

export default {
  theme: {
    extend: {
      fontFamily: {
        // Display fonts - bold, memorable headlines
        display: ["'Clash Display'", ...fontFamily.sans],
        heading: ["'Cabinet Grotesk'", ...fontFamily.sans],

        // Body fonts - refined, readable
        body: ["'Satoshi'", ...fontFamily.sans],

        // Mono fonts - for financial data/numbers
        mono: ["'JetBrains Mono'", ...fontFamily.mono],
        tabular: ["'IBM Plex Mono'", ...fontFamily.mono],
      },
    },
  },
};

Load fonts in layout.tsx:

tsx

import localFont from "next/font/local";
// Or from Google Fonts (less distinctive but easier):
import { Space_Grotesk, DM_Sans, Outfit } from "next/font/google";

const displayFont = localFont({
  src: "../fonts/ClashDisplay-Variable.woff2",
  variable: "--font-display",
  display: "swap",
});

// Apply to html
<html className={`${displayFont.variable}`}>

Typography Scale - Make It Count

tsx

// Headlines - BOLD statements
<h1 className="font-display text-6xl md:text-8xl font-bold tracking-tight leading-none">
  Short Interest
</h1>

// Subheadings - refined contrast
<h2 className="font-heading text-2xl font-medium text-muted-foreground tracking-tight">
  Australian Market Data
</h2>

// Data numbers - tabular, precise
<span className="font-tabular text-3xl tabular-nums tracking-tight">
  {shortPercent.toFixed(2)}%
</span>

// Eyebrow text - small but impactful
<span className="font-mono text-xs uppercase tracking-widest text-muted-foreground">
  Live Data
</span>

Color Systems

AVOID Clichéd Palettes

tsx

// ❌ NEVER - Purple gradients on white (AI slop signature)
className = "bg-gradient-to-r from-purple-500 to-pink-500";

// ❌ NEVER - Generic blue everything
className = "bg-blue-500 hover:bg-blue-600";

// ❌ NEVER - Washed out pastels without purpose
className = "bg-purple-100 text-purple-800";

CREATE Distinctive Palettes

Define in globals.css with CSS variables:

css

@layer base {
  :root {
    /* Signature accent - pick ONE memorable color */
    --accent: 142 76% 36%; /* Emerald for gains */
    --accent-foreground: 0 0% 100%;
    --accent-muted: 142 40% 90%;

    /* Semantic colors for financial data */
    --positive: 142 76% 36%; /* Gains - emerald */
    --negative: 0 84% 60%; /* Losses - red */
    --neutral: 220 9% 46%; /* Unchanged */

    /* Surfaces - create depth hierarchy */
    --background: 0 0% 100%;
    --surface-1: 0 0% 100%;
    --surface-2: 220 14% 96%;
    --surface-3: 220 13% 91%;

    /* Borders with intention */
    --border: 220 13% 91%;
    --border-subtle: 220 13% 95%;
    --border-strong: 220 9% 46%;
  }

  .dark {
    /* Dark mode: rich blacks, not muddy grays */
    --background: 224 71% 4%;
    --surface-1: 222 47% 8%;
    --surface-2: 222 47% 11%;
    --surface-3: 222 47% 14%;

    /* Accent POPS more in dark mode */
    --accent: 142 70% 45%;

    /* Borders subtle but present */
    --border: 222 47% 18%;
    --border-subtle: 222 47% 14%;
  }
}

Use semantically throughout components:

tsx

// Gains/losses with clear visual hierarchy
<Badge className={cn(
  "font-tabular tabular-nums",
  isPositive
    ? "bg-positive/10 text-positive border-positive/20"
    : "bg-negative/10 text-negative border-negative/20"
)}>
  {isPositive ? "+" : ""}{change.toFixed(2)}%
</Badge>

// Accent for primary actions
<Button className="bg-accent text-accent-foreground shadow-lg shadow-accent/25">
  View Details
</Button>

Motion & Animation

Configure in tailwind.config.ts

typescript

export default {
  theme: {
    extend: {
      animation: {
        "fade-in": "fadeIn 0.5s ease-out forwards",
        "slide-up": "slideUp 0.5s ease-out forwards",
        "slide-in-right": "slideInRight 0.3s ease-out forwards",
        "scale-in": "scaleIn 0.2s ease-out forwards",
        "pulse-subtle": "pulseSubtle 2s ease-in-out infinite",
        shimmer: "shimmer 2s linear infinite",
        glow: "glow 2s ease-in-out infinite alternate",
      },
      keyframes: {
        fadeIn: {
          "0%": { opacity: "0" },
          "100%": { opacity: "1" },
        },
        slideUp: {
          "0%": { opacity: "0", transform: "translateY(20px)" },
          "100%": { opacity: "1", transform: "translateY(0)" },
        },
        slideInRight: {
          "0%": { opacity: "0", transform: "translateX(20px)" },
          "100%": { opacity: "1", transform: "translateX(0)" },
        },
        scaleIn: {
          "0%": { opacity: "0", transform: "scale(0.95)" },
          "100%": { opacity: "1", transform: "scale(1)" },
        },
        shimmer: {
          "0%": { backgroundPosition: "-200% 0" },
          "100%": { backgroundPosition: "200% 0" },
        },
        glow: {
          "0%": { boxShadow: "0 0 20px rgba(16, 185, 129, 0.2)" },
          "100%": { boxShadow: "0 0 30px rgba(16, 185, 129, 0.4)" },
        },
      },
    },
  },
};

Staggered Reveals (High Impact)

One well-orchestrated page load creates more delight than scattered micro-interactions:

tsx

export function StockList({ stocks }: { stocks: Stock[] }) {
  return (
    <ul className="space-y-2">
      {stocks.map((stock, i) => (
        <li
          key={stock.code}
          className="animate-slide-up opacity-0"
          style={{
            animationDelay: `${i * 50}ms`,
            animationFillMode: "forwards",
          }}
        >
          <StockRow stock={stock} />
        </li>
      ))}
    </ul>
  );
}

Hover States That Surprise

tsx

<Card
  className={cn(
    "group relative overflow-hidden",
    "transition-all duration-300 ease-out",
    "hover:shadow-xl hover:shadow-accent/5",
    "hover:-translate-y-1",
    "hover:border-accent/50"
  )}
>
  {/* Background glow on hover */}
  <div
    className={cn(
      "absolute inset-0 opacity-0 transition-opacity duration-300",
      "bg-gradient-to-br from-accent/5 via-transparent to-transparent",
      "group-hover:opacity-100"
    )}
  />

  {/* Arrow that slides in */}
  <ArrowRight
    className={cn(
      "absolute right-4 top-1/2 -translate-y-1/2",
      "opacity-0 -translate-x-2",
      "transition-all duration-300",
      "group-hover:opacity-100 group-hover:translate-x-0"
    )}
  />

  <div className="relative z-10">{children}</div>
</Card>

Backgrounds & Atmosphere

Grid Patterns

tsx

// Subtle dot grid
<div className="absolute inset-0 bg-[radial-gradient(#e5e7eb_1px,transparent_1px)] [background-size:16px_16px] opacity-50" />

// Line grid
<div className="absolute inset-0 bg-[linear-gradient(to_right,#8080800a_1px,transparent_1px),linear-gradient(to_bottom,#8080800a_1px,transparent_1px)] bg-[size:24px_24px]" />

// Gradient grid for dark mode
<div className="absolute inset-0 bg-[linear-gradient(to_right,#ffffff05_1px,transparent_1px),linear-gradient(to_bottom,#ffffff05_1px,transparent_1px)] bg-[size:32px_32px]" />

Gradient Meshes & Orbs

tsx

<div className="relative overflow-hidden">
  {/* Gradient orbs for atmosphere */}
  <div className="absolute -top-40 -right-40 h-80 w-80 rounded-full bg-accent/20 blur-3xl" />
  <div className="absolute -bottom-40 -left-40 h-80 w-80 rounded-full bg-primary/10 blur-3xl" />
  <div className="absolute top-1/2 left-1/2 -translate-x-1/2 -translate-y-1/2 h-96 w-96 rounded-full bg-accent/5 blur-3xl" />

  {/* Content above the atmosphere */}
  <div className="relative z-10">{children}</div>
</div>

Noise Texture

Add to globals.css:

css

.noise-overlay::before {
  content: "";
  position: absolute;
  inset: 0;
  background-image: url("data:image/svg+xml,%3Csvg viewBox='0 0 256 256' xmlns='http://www.w3.org/2000/svg'%3E%3Cfilter id='noise'%3E%3CfeTurbulence type='fractalNoise' baseFrequency='0.65' numOctaves='3' stitchTiles='stitch'/%3E%3C/filter%3E%3Crect width='100%25' height='100%25' filter='url(%23noise)'/%3E%3C/svg%3E");
  opacity: 0.03;
  pointer-events: none;
}

Layout & Composition

Break the Grid

tsx

// Overlapping elements create depth
<div className="relative">
  <Card className="relative z-10">Main content</Card>
  <div className="absolute -bottom-4 -right-4 z-0 h-full w-full rounded-xl bg-accent/10" />
</div>

// Asymmetric layouts
<div className="grid grid-cols-12 gap-6">
  <div className="col-span-12 md:col-span-7">Large content area</div>
  <div className="col-span-12 md:col-span-5 md:-mt-12">Offset sidebar</div>
</div>

// Diagonal sections
<section className="relative -skew-y-3 bg-surface-2 py-24">
  <div className="skew-y-3">Content stays straight</div>
</section>

// Full-bleed with contained content
<section className="bg-surface-2">
  <div className="mx-auto max-w-7xl px-4 py-24">
    Contained content
  </div>
</section>

Generous Negative Space

tsx

// Let hero content breathe
<section className="py-32 md:py-48">
  <div className="mx-auto max-w-2xl text-center">
    <h1 className="text-5xl md:text-7xl font-display font-bold mb-8">
      One powerful statement
    </h1>
    <p className="text-xl text-muted-foreground leading-relaxed mb-12">
      Supporting text with room to breathe and be read.
    </p>
    <Button size="lg">Primary Action</Button>
  </div>
</section>

// Card grids with breathing room
<div className="grid gap-8 md:grid-cols-2 lg:grid-cols-3">
  {items.map(item => (
    <Card key={item.id} className="p-8">{item}</Card>
  ))}
</div>

Data Visualization with Visx

Chart Color Palette

tsx

// Define a distinctive palette
const CHART_COLORS = {
  // Primary series
  primary: "hsl(142, 76%, 36%)", // Emerald accent
  secondary: "hsl(220, 70%, 50%)", // Blue
  tertiary: "hsl(45, 93%, 47%)", // Amber

  // Semantic
  positive: "hsl(142, 76%, 36%)",
  negative: "hsl(0, 84%, 60%)",

  // UI elements
  grid: "hsl(220, 13%, 91%)",
  gridDark: "hsl(222, 47%, 18%)",
  axis: "hsl(220, 9%, 46%)",

  // Categorical palette (for multi-series)
  series: [
    "#10b981", // Emerald
    "#3b82f6", // Blue
    "#f59e0b", // Amber
    "#ef4444", // Red
    "#8b5cf6", // Violet
    "#06b6d4", // Cyan
  ],
};

// Gradient fills for area charts
<LinearGradient
  id="area-gradient"
  from={CHART_COLORS.primary}
  to={CHART_COLORS.primary}
  fromOpacity={0.3}
  toOpacity={0}
/>;

Chart Typography

  tickLabelProps={() => ({
    fill: "hsl(var(--muted-foreground))",
    fontSize: 11,
    fontFamily: "var(--font-mono)",
    textAnchor: "middle",

      className={cn(
        "animate-shimmer rounded-md",
        "bg-gradient-to-r from-muted via-muted-foreground/10 to-muted",
        "bg-[length:200%_100%]",
        className
      )}
    />
  );
}

// Usage
<Skeleton className="h-8 w-32" />
<Skeleton className="h-4 w-full" />

Glass Morphism

    "border border-white/10",
    "shadow-xl shadow-black/5"
  )}
>
  {children}
</Card>

Data Badge with Glow

tsx

<span
  className={cn(
    "inline-flex items-center gap-1 px-2 py-0.5 rounded-full",
    "font-tabular text-sm tabular-nums",
    isPositive && "bg-positive/10 text-positive shadow-sm shadow-positive/20",
    !isPositive && "bg-negative/10 text-negative shadow-sm shadow-negative/20"
  )}
>
  {isPositive ? (
    <TrendingUp className="h-3 w-3" />
  ) : (
    <TrendingDown className="h-3 w-3" />
  )}
  {value}%
</span>

Anti-Patterns Checklist

Before shipping, verify you haven't fallen into these traps:

❌ AI Slop	✅ Distinctive
`font-sans` (Inter/system)	Custom display + body fonts
Purple-pink gradient	Single memorable accent color
`bg-blue-500` buttons	Accent with shadow glow
Even spacing everywhere	Intentional rhythm, generous whitespace
Plain white background	Subtle patterns, gradients, depth
Generic card borders	Hover states, subtle shadows, glow
Static page load	Staggered animations, reveals
Same design every time	Unique aesthetic per context

Final Checklist

• Font choice: Is it distinctive and memorable?
• Color palette: Does the accent pop? Is there one signature color?
• Animations: Is page load orchestrated with staggered reveals?
• Hover states: Do interactive elements surprise and delight?
• Dark mode: Does the design shine even more in dark?
• Negative space: Is there room to breathe?
• Details: Borders, shadows, transitions - all intentional?

Remember: Claude is capable of extraordinary creative work. Don't hold back - show what can truly be created when thinking outside the box and committing fully to a distinctive vision.
