-# Icon Placeholder
-# 
-# This is a placeholder for the bundle icon.

-# 2. Place it at assets/icon.png
-# 3. Remove this placeholder file
-#
-# Suggested icon concepts:
-# - Obsidian logo combined with AI/connection symbols
-# - Brain/network icon in Obsidian's purple color scheme
-# - Document/note icon with chat/conversation elements
