qbz/crates/qbz-qt/qml/views/local/LocalScanProgress.qml

// Compact, read-only progress for the Local Library header. It combines the
// authoritative folder scanner with the derived catalog projection, but
// never reads rows from either model: only bounded counters cross into QML,
// preserving native paging and first-paint performance.
