/**
 * Real device-emulated mobile tests.
 *
 * Runs on mobile-chromium (Pixel 7) and mobile-webkit (iPhone 14) projects
 * with real touch, mobile UA, DPR, and (for iPhone) the WebKit engine.
 * Replaces the old resized-desktop approach in gui-visual-mobile / gui-responsive.
 *
 * All tests are tagged @mobile so the device projects' grep filter picks them up.
