- Line 351: Update the carousel animation configuration near scrollX so the
indicator width animation uses the JavaScript driver by setting useNativeDriver
to false; do not use the native driver unless the animation is changed to a
supported transform or opacity property.

definitions, and both improvingux.md definitions.

site:reactnative.dev/docs/animations useNativeDriver width layout properties native driver Animated
💡 Result:
In React Native, the Animated library's native driver (enabled via useNativeDriver: true) does not support animating layout properties, such as width, height, or other Flexbox and position-related styles [1][2][3]. The native driver is designed to run animations on the UI thread to ensure smooth performance by offloading work from the JavaScript thread [1][3]. Because of this architecture, it is currently limited to animating non-layout properties, primarily those that do not trigger a relayout of the component tree, such as transform (e.g., scale, rotation) and opacity [1][2][3]. If you need to animate layout properties like width or height, you have a few alternatives: 1. LayoutAnimation: This API is specifically designed for animating layout changes. It allows you to globally configure animations for the next render or layout cycle, making it ideal for Flexbox-based transitions without needing to manually calculate property changes [1][2]. 2. Animating via Transform: If possible, use the transform property (e.g., scaleX, scaleY) instead of changing the actual width or height. Animating transforms is supported by the native driver and is generally more performant than animating layout properties. 3. JavaScript-based Animations: If layout animation is strictly required and cannot be achieved via transforms or LayoutAnimation, you can perform the animation without useNativeDriver: true. Be aware that this runs on the JavaScript thread and may experience frame drops if the thread becomes blocked [1][2].

Keep the carousel event on the JavaScript driver.
scrollX drives the indicator width style. The native driver does not support layout properties such as width, so the indicator cannot animate correctly with useNativeDriver: true. Keep useNativeDriver: false, or animate a supported transform or opacity property instead.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Import ComponentRef explicitly in all six TypeScript Snack examples.
Each block imports named values but no local React namespace. Under the example TypeScript configuration, React.ComponentRef can produce TS2686. Add import type {ComponentRef} from 'react'; and replace React.ComponentRef in all affected locations: both legacy definitions, the new-architecture definition, the DrawerLayoutAndroid definition, and both improvingux.md definitions.

概要
已将 upstream/main 合并并推送到
production（50923642f2），随后同步实际落后的中文文档。文档同步
animated、animatedvaluexy、animations、panresponder增加/校正useNativeDriver配置。appstate、dimensions、drawerlayoutandroid、flexbox、improvingux、layout-props、legacy/direct-manipulation、linking、progressbarandroid、stylesheet、text-style-props、the-new-architecture/direct-manipulation。statusbar：增加auto样式并补全中文类型说明。view-style-props：新增backgroundPosition、backgroundRepeat、backgroundSize中文说明与示例。cnwebsite 同步
website/package.json的@types/react精确版本约束（移除 CN 配置中的 caret）。docs.path和中文侧边栏保持不变。已核验但未改动
colors与the-new-architecture/fabric-component-native-commands没有本次上游文档 diff；pure-cxx-modules、turbo-native-modules的上游变动仅涉及其 MDX 动态版本命令，CN 对应页面维持既有静态 shell 命令，未进行不必要重写。验证
