name: Dependabot dedupe
# Dependabot opens a PR after a bump, but `pnpm install` alone doesn't
# dedupe peer copies of packages (e.g. two versions of i18next, each
# holding their own singleton state). That split caused a hydration
# mismatch on #272 until a manual `pnpm dedupe` collapsed them.
#
# This workflow fires on every dependabot PR, runs `pnpm dedupe`, and
# pushes the resulting lockfile update back to the PR branch so the
# subsequent CI run tests the deduped tree.
#
# Requires `DEPENDABOT_DEDUPE_TOKEN` — a repo secret holding a
# fine-grained PAT (or GitHub App token) with `contents: write` on
# this repo. The default `GITHUB_TOKEN` would work for the push but
# would NOT trigger a subsequent CI run on that push (GitHub's
# anti-loop safeguard), leaving the PR with stale green CI from
# before the dedupe commit. A PAT re-triggers CI so the reviewer
# sees test results for the state they'd actually be merging.
