+# Home Page Design Override
+
+## Purpose
+This file contains **page-specific design rules** that **override** the master design system for the Home page.
+
+## Key Differences from Master
+
+### Layout Structure
+- **Hero Section**: Full-width gradient banner with quick picks
+- **Horizontal scrolling sections** for album/playlist rows
+- **Grid layout** for featured content (3 columns desktop, 2 tablet, 1 mobile)
+- **Sticky sub-navigation** for content categories
+
+### Visual Hierarchy
+1. **Greeting & Quick Picks** (hero section) - Highest prominence
+2. **Featured Playlists** - Large cards with gradients
+3. **Recently Played** - Horizontal scroll row
+4. **Made For You** - Grid of recommendation cards
+5. **New Releases** - Compact list view
+
+### Section Spacing
+- Hero padding: **60px** (larger than master)
+- Section gaps: **48px** (between major sections)
+- Row padding: **24px** (within sections)
+
+## Components
+

+
+## Additional Anti-Patterns for Home
+
+❌ **NEVER load all content at once** - Implement lazy loading for rows
+❌ **NEVER auto-play audio on home** - User must explicitly click play
+❌ **NEVER mix card sizes in same row** - Keep consistent sizing
+❌ **NEVER hide horizontal scroll indicators** - Show shadow hint
+❌ **NEVER use generic greetings** - Personalize with time of day
+❌ **NEVER skip section anchors** - Allow deep linking to sections
