# The settings we assert live in .chezmoitemplates/claude-settings.json as plain
# JSON -- edit that file, not this one.
#
# They are MERGED into the existing file rather than replacing it, because
# Claude Code writes here too: autoMode.environment is regenerated per machine
# and /config edits land in this file. jq's `*` operator merges recursively, so
# nested objects survive; only the keys named in claude-settings.json are
# overwritten.
