Qobuz fills missing credits with strings such as "Not Documented", "Unknown Artist" or "N/A". `qbz_text_utils::names::is_placeholder_name` recognises them (case-insensitive, hyphen/underscore folded) and the album document, the track info modal and the album info modal drop those names from credits, composers, featured lists and the header's artist fallback, dropping a row entirely when nothing legible is left. cc
