/* ============================================================
   PyGround "Soft/Premium" Redesign-Layer (2026-05-30)
   Laedt NACH styles.css und ueberschreibt nur den globalen Look:
   warmes Anthrazit + Blau-Tuerkis-Akzent, randlose Cards, weiche Elevation.

   Akzent 2026-06-01 von Violett zurueck auf Blau-Tuerkis gestellt
   (das alte Schema: #3b82f6 -> #10b981).

   BEWUSST AUSGENOMMEN (damit Syntax-Highlighting + interaktive
   Python-Skripte / Pyodide unveraendert funktionieren):
     .content-body pre, .content-body code, .ace-* / .ace_editor,
     .local-py-*, .webllm-*, .pgllm-*, .pgmcp-*
   Diese behalten bewusst ihren dunklen Code-Look.
