# Keep the add-on's own artifacts out of git, in every project it is installed in.
#
# Rewrites a marker-delimited block in the project's .git/info/exclude. That file is
# per-clone and never committed, and every git process honours it -- unlike
# core.excludesfile, which is set on the container's git config only and so does
# nothing for git run from the host. Called by install.sh, which runs on "ddev start"
# and on every "ddev claude", so the list refreshes itself as the add-on changes.
#
# Personal patterns (.DS_Store, .idea, CLAUDE.md, ...) are deliberately NOT here:
# they belong in ~/.gitignore_global, not to this add-on.
