The previous commit message said I added data-testid="player-bar-compact"
+ "player-bar-desktop" to PlayerBar.svelte but the edits actually
dropped silently — only the test file changes landed. Without the
testids, the test file's within(getByTestId(...)) calls all fail.
This adds the actual attributes.
