CRITICAL — Color System

Rule 1: Always Use Semantic Color Roles — Never Hardcode

// ✅ Every color references MaterialTheme
Text(color = MaterialTheme.colorScheme.onSurface)           // primary text
Text(color = MaterialTheme.colorScheme.onSurfaceVariant)    // secondary text
Box(Modifier.background(MaterialTheme.colorScheme.surfaceContainerLow))  // card bg
Icon(tint = MaterialTheme.colorScheme.onSurfaceVariant)     // secondary icon
