      # Pull the auto-update manifest from the latest stable release so that
      # any deploy of `website/` (including blog posts, doc tweaks, roadmap edits)
      # republishes /update/latest.json. Strategy:
      #   1. Try the GitHub release's latest.json. If valid (darwin-aarch64 +
      #      windows-x86_64 present), use it.
      #   2. If the release manifest is missing or partial (matrix race
      #      condition, mid-release moment, etc.), fall back to the manifest
      #      currently served by https://gitwand.app/update/latest.json.
      #      That guarantees the auto-update keeps pointing at the last known
      #      good version, even when the website is redeployed for an unrelated
      #      reason (changelog update, doc tweak…).
      #   3. If both are missing, deploy the website without /update/latest.json
      #      — auto-update will be temporarily unavailable but the site itself
      #      stays publishable (changelog, docs, README are independent of the
      #      updater).
