/* ==========================================================================
   Responsive
   Strategie:
   - >1300px (Desktop): volles 4-Spalten-Layout (Sidebar/Center/HUD-rechts/
     Reasoning) wie gebaut.
   - 901-1300px (kleinerer Desktop/Laptop): HUD-Spalte rechts und
     Reasoning-Panel ausblenden (Platzgrund), Sidebar bleibt im Fluss.
   - <=900px (Tablet quer, große Phones) bis runter zu ~375px (Phone hoch):
     Sidebar UND Reasoning-Panel werden zu Overlay-Drawern (fixed, volle
     Hoehe, per .open-Klasse eingeblendet) statt fix nebeneinander gequetscht
     zu werden -- gleiches Prinzip wie das bereits vorhandene Ein-/Ausklappen,
     nur dass "ausgeklappt" auf schmalen Screens als Overlay über dem Chat
     liegt statt das Grid zu stauchen. Topbar bricht in zwei Zeilen um
     (Persona-Switcher auf eigene volle Breite), damit kein Button/Tab
     abgeschnitten wird oder Text wie "G R O O T" buchstabenweise umbricht.
   - iPad-Portrait (768-1024px, Hoch) bekommt ein eigenes Zwischen-Layout.
