Single homes for logic that was copy-pasted across screens: the settings collapsing header, album detail header (online screen's design as the reference), selection pill button + bottom-bar chrome, disc separator chip, error card, cover URL upgrade, byte/clock formatting, duration extraction, UnifiedLibraryItem (moved out of the queue_tab library so other screens can import it), and the batch convert/ReplayGain engine keyed on it.
