/* Wraps the rail + session views so we can swap the rail position without
   touching the rail or view components themselves. Four positions:
     rail-top    — rail above messages (default)
     rail-bottom — rail under everything (below the input bar)
     rail-left   — rail down the left side
     rail-right  — rail down the right side
   The DOM is `.dashboard-body > .session-rail-container > .session-rail`
   (with `.session-views-container` as the rail-container's sibling). For
   left/right we make the rail-container the column-sized flex item; for
   top/bottom we flip the dashboard-body's main axis (column / column-reverse). */
