   CS2STAT — shell.css
   Application shell: left sidebar (desktop), in-content topbar, main content
   area, and the mobile bottom navigation. Also the minimal auth-shell used for
   anonymous pages (login / register).

   Breakpoint: 768px (mobile < 768), matching base.html + replay_player.js.
   The 2D viewer (viewer_2d.html) does NOT use this shell.
