@* Invariant trio shared by every medium's detail page: a back link, a masthead (title + artist),
   a play/share affordance row wired to the streaming player, and slots for the medium-specific
   hero visual and metadata block. TrackDetail and the Session/Mix detail pages all compose this;
   per-medium variance rides the Hero and MetaContent render fragments. *@

<div class="deepdrft-track-detail-container">

    @* Back link top-left, optional medium action top-right, on one SpaceBetween row. The action slot
       stays null for media that don't supply it (Track/Session), so they render the back link alone. *@
