+/// Track metadata fetch abstraction with two render-mode-specific implementations:
+///
+///   - Server prerender pass: <c>TrackDirectDataService</c> in the DeepDrftPublic host
+///     resolves <see cref="DeepDrftData.ITrackService"/> in-process (EF Core / SQL) and
+///     avoids a loopback HTTP hop.
+///   - WASM interactive pass: <c>TrackClientDataService</c> in this assembly delegates
+///     to <see cref="Clients.TrackClient"/> over HTTP.
+///
+/// Components inject this single seam so they do not branch on render mode.
