Pitchfork (Blog/Editorial Reference)

URL: https://pitchfork.com/

Editorial Patterns:

• Large featured hero with editorial image
• Generous whitespace (32px+ margins)
• Strong typographic hierarchy
• Serif fonts for article content emphasis
• Category labels and review scores
• Author attribution with avatars

Spotify Encore (Token System Reference)

URL: https://spotify.design/article/reimagining-design-systems-at-spotify

Token-Based Approach:

• Foundation → Web/Mobile → Local systems
• Consistent spacing scale (4px base unit)
• Color semantic naming (background, surface, text)
• Motion tokens for animations
• Component-level consistency

---

CRITICAL: Theme Token Requirement

NEVER approve code with hardcoded colors. All styling MUST use Tailwind theme tokens.

Copy// ❌ REJECT - Hardcoded colors
className="bg-[#0a0a0a] text-[#ffffff] border-[#262626]"
className="bg-neutral-800 text-gray-100"  // Also bad - not theme-aware

// ✅ APPROVE - Theme tokens only
className="bg-background text-foreground border-border"
className="bg-card text-muted-foreground"

Available Tailwind Theme Tokens (defined in globals.css):

When reviewing, check:

• No hex codes in className (e.g., bg-[#...])
• No arbitrary Tailwind colors (e.g., bg-neutral-800)
• All colors use semantic tokens (e.g., bg-background)

Design Review Checklist

When reviewing any UI implementation, check these criteria:

Layout & Spacing

• Uses consistent spacing scale (4, 8, 12, 16, 24, 32, 48px)
• Grid-based layout with proper responsive breakpoints
• Proper visual hierarchy established
• Content density matches Billboard (not too sparse, not cluttered)

Typography

• Headlines are bold/semi-bold, 24px+ for primary
• Body text uses system/Inter font, 14-16px
• Text colors: primary (#ffffff), secondary (#a3a3a3), muted (#525252)
• Line heights provide good readability

Color & Theme

• Dark theme as default
• Background: #0a0a0a to #171717 range
• Card surfaces: #262626 with subtle borders
• Accent red (#ef4444) used sparingly for CTAs
• Sufficient contrast ratios (WCAG AA minimum)

Components

• Video cards use 16:9 aspect ratio
• Hover states with subtle scale/overlay effects
• Consistent border-radius (8px for cards, 4px for small elements)
• Loading skeletons match component structure

Motion & Interaction

• Hover effects: subtle scale (1.02-1.05) or brightness
• Transitions: 150-300ms duration
• Ease-out or spring curves for natural feel
• No jarring animations

Quick Reference: Tailwind Token Usage

Use these Tailwind classes (NOT hex codes):

Copy// Backgrounds
bg-background       // Page base (#0a0a0a dark)
bg-card             // Elevated surfaces (#171717)
bg-secondary        // Secondary surfaces (#1c1c1c)
bg-muted            // Subtle backgrounds

// Text
text-foreground          // Primary text (white)
text-muted-foreground    // Secondary text (gray)
text-card-foreground     // Text on cards

// Borders
border-border       // Standard borders
border-input        // Form input borders

// CTAs & Accents
bg-primary text-primary-foreground           // Billboard red button
bg-success text-success-foreground           // Green positive action
bg-destructive text-destructive-foreground   // Red danger action

// Hover states
hover:bg-primary/90     // Subtle darken
hover:text-foreground   // Text highlight
hover:border-foreground // Border highlight

Spacing Scale (Tailwind):

Copygap-1 (4px)   gap-2 (8px)   gap-3 (12px)  gap-4 (16px)
gap-6 (24px)  gap-8 (32px)  gap-12 (48px) gap-16 (64px)

Motion:

Copytransition-colors duration-200   // Color transitions
transition-transform duration-300 ease-out  // Scale/position
