# theme. That is what turned the editor white twice, and it happened a third time during the
# 2026-07-25 rename (the settings still said "Adom Inverse" after the theme became "Adom Studio
# Bright Inverse"). Every one of those looked completely fine in the config.

# Exit 0 = the installed pack and the live setting agree with what HD expects.
