landscape navbar centering: reset portrait margin-right on .container-fluid + margin-left on .navbar-brand so sidebar contents align to horizontal centre; showGuard gains invertY option for modal-grid callers (role-select cards fly away from centre); gameboard.js showPortals gains viewport-half detection so game-kit tooltips show below when tokens are in upper half (landscape clip fix); position-strip top: 0; tighten gear-btn btn-abandon selector to #id_room_menu scope
