   allein-unter-menschen.de — eigenstaendiges Theme
   -----------------------------------------------------------------------------
   Begleit-Site zum Sachbuch "Allein unter Menschen: Warum Einsamkeit unsere
   Gesellschaft veraendert" von Stephan Paul. Bewusst NICHT von
   theme-watch-and-alert, theme-php-buch, theme-windows-absichern oder
   theme-mesh-verstehen abgeleitet -- eigene Variablen mit "aum-"-Prefix,
   eigenes Farbsystem.

   Bildsprache: direkt aus dem cover_prompt des Buchs abgeleitet (siehe
   /srv/8tb/ai-storage/Buch-Creator/work_einsamkeit/project_config.json) --
   ein einzelnes kleines warmes Licht (Amber/Terrakotta) in einem weiten,
   stillen dunklen Raum (dunkles Dusky-Blau/Anthrazit). Anders als
   windows-absichern.de und mesh-verstehen.de (beide hell, freundlich)
   ist dieses Theme bewusst DUNKEL: die Farbwelt traegt den Buchinhalt
   (Einsamkeit, Isolation, aber auch leise Hoffnung), keine Kompromiss-
   Aufhellung fuer "Web-Freundlichkeit".

   Kein wiederkehrendes Maskottchen (anders als windows-absichern.de) --
   dieses Buch hat keine Titelfigur, die Bildsprache ist rein abstrakt/
   atmosphaerisch, ausdruecklich ohne sichtbare menschliche Gesichter.
   -----------------------------------------------------------------------------
   Konvention: jeder Selektor und jede Variable mit .aum- / --aum- Prefix,
   damit das Theme in dieser Multi-Site-Contao-Instanz kollisionsfrei
   koexistiert.
