Field notes
The workstation separates full library access from single-file playback. Its USB path depends on the File System Access API and reads a rekordbox export.pdb plus three files per track instead of bulk-copying the drive. The interface also reports browser audio measurements—base latency, output latency, callback rate, and underruns—and offers a same-network phone surface. Safari and Firefox are explicitly excluded from the mounted-drive workflow.
