// Browse scenario driven ENTIRELY with real mouse/keyboard input via xdotool
// (see human.mjs). Connects to a Chrome already running with
// --remote-debugging-port (default 9222) on the streamed X display.
//
// All ACTIONS are real input: address-bar navigation (Ctrl+L + typing),
// search typing, clicking the video, the settings gear -> 화질 -> 1080p menu,
// the autoplay toggle, the play button, fullscreen via the 'f' key, scrolling,
// and entering 나무위키. The CDP/DOM API is used ONLY to read state for
// verification (paused/quality/fullscreen) and as a rare click fallback when an
// element has no on-screen box.
