"""
    A RoboFont script to check if "dark mode" is currently active and apply dark preferences in RoboFont if so.
    
    Works best if set up as a "Start Up Script." Here’s how to make it one:
    
    1. Open RoboFont > Preferences
    2. Go to Extensions > Start Up Scripts
    3. Click the "+" icon, then add this script
    4. Click "Apply" to save setting changes
    5. Restart RoboFont!
 
    ----
    
    Possible Script To-Do Items:
    - Auto-switch light/dark when OS setting changed. Possibly: run script every n seconds to automatically catch if the light/dark mode changes.
    - Handle Font View colors better (this is somewhat limited by RoboFont itself, but may may have a clever solution or improve over time).
