 - **C++ style engine**: Forged on the 2nd-gen Unistyles C++ engine. Injects styles directly into the ShadowTree without triggering React re-renders — a direct, optimized highway between classNames and the native layer

 - **Native insets & runtime values**: Automatic safe area injection, device rotation, and font size updates — no `SafeAreaListener` setup needed

 No code changes needed — props connect directly to C++ engine, eliminating re-renders automatically.
 
+### Group Variants
+
+Tailwind `group` variants propagate parent interaction state to descendants through the C++ shadow tree. No re-renders, no context providers.
+
+```tsx
+// Basic group — descendants react to parent press
+<Pressable className="group p-4 bg-base rounded-xl">
+  <Text className="text-default group-active:text-primary">Press the card</Text>
+  <View className="size-8 bg-blue-500 rounded group-active:bg-red-500" />
+</Pressable>
+
+// Named groups — descendants pick which ancestor to follow
+<Pressable className="group/card p-4 bg-base rounded-xl">
+  <Pressable className="group/button px-3 py-1 bg-primary rounded">
+    <Text className="text-white group-active/card:opacity-50 group-active/button:font-bold">
+      Nested groups
+    </Text>
+  </Pressable>
+</Pressable>
+```
+
+**Supported variants**: `group-active:*` (press), `group-focus:*` (focus). Named variants: `group-active/{name}:*`, `group-focus/{name}:*`.
+
+**Supported group parents**: `Pressable` (press + focus), `Text` (press — requires `onPress`, even empty). `TouchableOpacity`, `TouchableHighlight`, `TouchableWithoutFeedback`, and `TextInput` do **not** act as group parents — wrap in a `Pressable` marked `group`.
+
+**Not supported**: `group-hover:*` (no pointer hover on native), `group-disabled:*` (parsed but no shadow tree trigger), arbitrary `group-[.selector]:*` variants, implicit `in-*` variants.
+
 ### Suspense Support
 
 Components inside React `Suspense` boundaries are handled correctly. While a subtree is suspended, Uniwind keeps the C++ shadow entries alive so theme updates and runtime changes (dark mode, orientation, etc.) still reach suspended nodes. When the tree unsuspends, styles are already up to date — no flash of stale theme.
