Add StateChanged multicast event to IPlayerService so AudioPlayerBar and TracksView
re-render themselves without relying on the IsFixed cascade re-render path. Clear
_selectedTrack in TracksView when IsLoaded drops (stop, unload, end-of-track). Set
IsLoaded=false in OnPlaybackEndCallback so end-of-track triggers the same clear path.
Add JS-module readiness probe in AudioInteropService; delete dead TS and buffered C#
path; consolidate GetPlayIcon/FormatTime helpers; fix misleading minimize dock icon.
CMS pages were calling api/cms/track on https://localhost:5001 (the public host)
because the DeepDrft.API named client was base-addressed there; controllers live
on the Manager. Re-pointed to baseUrl. /cms page declared InteractiveAuto in a
Server-only host. App.razor link for MudBlazorThemeManager.css had _ outside the
@Assets[] expression. Public connections example carried a leftover Auth string.
