凱兒 10 年來一直擔任 ChickenChef.com 的行銷主管。這個網站從建立至今都使用同一個網頁應用程式平台，凱兒認為是時候更新為漸進式網頁應用程式 (PWA) 了。 如果 ChickenChef.com 改用 PWA 平台，可享有哪兩項優勢？請選擇最合適的答案。

Progressive Web Apps (PWAs) offer several advantages, two of which are direct accessibility from the mobile home screen and offline functionality. PWAs can be "installed" to a user's home screen, providing an app-like experience without needing an app store. They also leverage service workers to cache resources, allowing them to function even with unreliable or no network connectivity. "降低裝置耗電量" (Reduced device power consumption) is not a primary, guaranteed benefit of PWAs; their power usage is comparable to regular web pages. "全面受到 Android 和 iOS 裝置支援" (Fully supported on Android and iOS devices) is partially true, but iOS support for all PWA features, especially push notifications, has historically been less robust than Android. "在應用程式商店中自動通過認證" (Automatically certified in app stores) is incorrect; PWAs bypass app stores entirely, which is a key advantage.
