/* The window is a flex column: header → brain-content → panel-container → footer.
   brain-content serves DUAL ROLE:
     1. As flex ITEM in the window column → needs flex:1 to fill space
     2. As flex CONTAINER for sidebar + main-view → needs flex-direction: row
   brain.css sets height:calc(100%-44px) which breaks the flex footer flow.

   (that's handled by .context-cockpit-layout → row). */
