/**
 * PWAInstallButton.tsx — A ready-to-use, fully styled React component.
 *
 * Renders an install button that:
 * - Automatically hides when the app is already installed or unsupported
 * - Shows a native install prompt on Android/Chrome
 * - Shows iOS instructions via a popover on iOS Safari
 * - Accepts full styling customization via className / style props
 *
 * Usage:
 *   <PWAInstallButton appName="My App" themeColor="#6200ee" />
 *
 * Or custom children:
 *   <PWAInstallButton appName="My App">
 *     <MyCustomButton />
 *   </PWAInstallButton>
