/*
 * Native App Styles
 *
 * Styles specifically for Hotwire Native apps (iOS/Android).
 * This stylesheet is loaded when the app is detected as a native app.
 *
 * Keep this file minimal - prefer Tailwind utilities in views for responsive design.
 * This file should only contain:
 * - Safe area handling
 * - Native header/footer styles
 * - Touch target enforcement
 * - View transitions
 * - Utility classes for hiding elements in native apps
