+# RACI-Konsolen-Board — Blender-Generator (bpy)
+# SLC-Workshop Tabletop · Einheiten: 1 Blender-Unit = 1 mm
+# Baut das Board parametrisch mit gefasten Kanten (Bevel), Mulden, Sektoren,
+# gravierten Labels, Action-Card-Steckschlitz; rendert eine Vorschau und
+# exportiert eine STL. Startgeruest v1 — in Blender 4.x getestet gegen die API,
+# einzelne Schritte sind per try/except abgesichert (Labels optional).
+#
+# Lauf:  Blender -> Scripting -> Open -> Run     ODER     blender -b -P raci-board.py
