The artist screen's "show all albums" overlay state was plain remember(), so navigating into an album and pressing back reset it — dumping you on the collapsed artist page instead of the list you came from. Persist which section is open via rememberSaveable (a String? title) so it survives the round-trip, and re-derive the overlay entries from the (surviving) categorized albums.
