/* ============================================================================
   screens.css — Layout der vier Hauptansichten
   ----------------------------------------------------------------------------
   Setzt das Layout für jeden der bestehenden Screens (#loginView,
   #mainMenuView, #lobbyView, #roomView, #statsView) sowie für den neuen
   #loadingView (Welle 1.7). IDs bleiben unverändert, damit die Test-Suites
   und der DOM-Stub weiterhin zielen.

   Cosmic-spezifisches Hinzu: .phone-Container (cosmic.html:140-147) und
   .loading-screen samt der drei SVG-Loader. Klassen für Menü-Grid, Lobby,
   Room, Sidebar, Canvas-Wrap, Overlay, Countdown, Chat, Spielerliste,
   Turnier-Hilfe und Series-HUD.

   Welle 2/3 ergänzen: .invite-bar → .code-pill-Umbau, Bottom-Sheet .sheet,
   Auth-Screen (#authView als #loginView-Alias).
   ============================================================================ */

/* ── Phone-Container (cosmic.html:140-147) ──────────────────────────── */
/* Phase 2 / Task #5: Front Page ist auf Phone und Desktop die gleiche
   schmale Spalte (~460px). .phone innerhalb einer Screen-Ansicht
   zentriert sich, ausserhalb (z. B. als App-Rahmen fuer loading) full-
   width.

   Phase 4: .app-shell ist der neue, container-skalierende Wrapper für
   Menü/Lobby/Stats/Login. Auf Phone (≤ 480 px) bleibt die Spalte 460 px
   schmal, ab Tablet dehnt sie sich bis 720 px, ab Desktop bis 1280 px.
   .phone bleibt als Klassen-Alias erhalten (Login-Card und andere
   Alt-Stellen verweisen teils noch darauf) und delegiert an die
   App-Shell-Regeln. */
