 The layout follows [IINA's video-first window](https://iina.io/img/screenshot.png) and the supplied screenshots: a 32-point frosted titlebar with native traffic lights and file icon, plus a dark frosted 440 × 68-point floating controller. AppKit materials blur the video beneath the chrome; muted icons, an orange volume track, a narrow seek thumb, and zero-padded time labels follow the reference. Shared vertical padding and an optical offset for symbol/slider insets balance the controller's visible top and bottom margins in both play and pause states. The controller starts centered with a four-percent bottom inset and keeps its relative position when the window changes size.
 
+The empty player uses the same HUD-glass material, 12-point rounded corners, and muted icon/text palette in a centered welcome card. File and YouTube opening actions share a consistently sized row; the card fits the 400 × 240-point minimum window, and the full window still accepts media-file and YouTube-link drops.
+
 Opening video fits the window to its display aspect ratio, including non-square pixels, and constrains subsequent window resizing. Fullscreen retains the normal letterboxed renderer; audio-only playback and close release the aspect constraint. Extreme ratios that cannot fit both the screen and usable controls keep a freely resizable letterboxed window.
 
 **Compact mode** uses the same window, Metal view, and playback session—not a second window or macOS system PiP. Use the PiP-shaped button in the normal playback controls, **⌃⌘P**, or **Playback Actions → Enter Compact Mode**. The compact-mode button replaces the fullscreen button; fullscreen remains available through its menu, keyboard shortcuts, and double-clicking normal-mode video. Compact mode starts at the current screen's top-right corner with a 16-point inset and a preferred width of 320 points, preserving display aspect where usable screen bounds and the 160 × 90-point minimum allow; extreme ratios retain letterboxing. Compact mode floats above ordinary windows, joins all Spaces, and is configured to join eligible other-app fullscreen spaces and Stage Manager sets. Small hover controls provide play/pause, restore, and Playback Actions; keyboard playback controls remain available.
