+```
+
+## Inline Variant Pattern (Preferred)
+
+Use inline object indexing instead of external config objects:
+
+```tsx
+// PREFERRED - inline object indexing
+<Box
+  h={{ lg: '48px', md: '40px', sm: '32px' }[size]}
+  bg={{ primary: '$primary', secondary: '$gray100' }[variant]}
+/>
+
+// AVOID - external config object
+const sizeStyles = { lg: { h: '48px' }, md: { h: '40px' } }
+<Box h={sizeStyles[size].h} />  // unnecessary indirection
+```
+
 ## Anti-Patterns (NEVER do)
 
 | Wrong | Right | Why |
 |-------|-------|-----|
 | `<Box style={{ color: "red" }}>` | `<Box color="red">` | style prop bypasses extraction |
+| `<Box {...css({...})} />` | `<Box className={css({...})} />` | css() returns string, not object |
 | `css({ bg: variable })` | `<Box bg={variable}>` | css()/globalCss() only accept static values |
+| `$color` in external object | `var(--color)` in external object | $color only transformed in JSX props |
 | No build plugin configured | Configure plugin first | Components throw at runtime without transformation |
 | `as any` on style props | Fix types properly | Type errors indicate real issues |
