/* =========================================================================
   Spotiny · Recommendations rail (v2 — dark premium redesign)
   --------------------------------------------------------------------------
   Horizontal scrolling rail of recommended tracks, shown on the home view.
   Recs are seeded from listening history (top artists + genres) and
   fall back to genre-based queries when no history exists.
   Uses fixed --card-w × --card-h sizing on every card.
