The quiz (song, playlist, players, music player and the popups opened from
it) moves into Quiz.tscn and the top panel into TopBar.tscn. The main window
keeps only the top bar, the quiz and the popups opened from the top bar, so
other views can be added next to the quiz later. Every node keeps its place
on screen.
Screenshots of every UI state before and after are pixel-identical, and a
layout test checks each node against a baseline taken before the split.
Popups:
- All nine popups now extend a shared PopupWindow class with open(),
close() and toggle(), instead of each copying its own close-on-click
code. Popups that need cleanup override close().
- A click outside a popup closed it and also pressed whatever was
underneath, e.g. Reset playlist. The closing click is now consumed.
- Popups used Godot's see-through default panel, so the song list and
titles showed through. They now use an opaque popup theme, and a
backdrop dims the window behind them.
- The main window root now fills the screen, so the backdrop covers it.
Text and images:
- Many labels and buttons forced nearest filtering, which made text and
icons jagged when the window is not 1920x1080. They now use the
default smooth filtering. Only the pixel-art "no character" picture
keeps nearest filtering when the winner window enlarges it.
Player list:
- A long player name pushed that row's character and buttons to the
right. Names now take the free space and shorten with an ellipsis, so
all rows line up and use the full width of the panel.
