# Points `core.hooksPath` at `scripts/hooks/` so the hook files are versioned
# with the repo instead of copied into `.git/hooks` (a stale copy can't drift
# out of date this way). Currently:
#
#   pre-push   — mirror prod + tags to the Gitea fallback (git.ranio.xyz)
#   post-merge — same, after a `git pull`/merge while on prod
#
# The mirror itself lives in `scripts/mirror-gitea.sh`; run it by hand any time
# with `scripts/mirror-gitea.sh`. Gitea is a just-in-case copy: GitHub is the
# source of truth, and a Gitea outage never blocks a push.
