  # Daily sweep for new community YouTube tutorials about Open Design. New
  # candidates are posted to Feishu for a maintainer to review — this workflow
  # does NOT generate entries or open PRs. A maintainer replies with which
  # candidates to publish, and the selected videos are turned into entries via
  # scripts/youtube-tutorials/generate-selected.ts (run by a maintainer, who
  # opens the PR).

  # Manual trigger: force a sweep outside the daily schedule. Leave days empty to
  # use the same gap-free watermark (since the last successful run) the schedule
  # uses; set it to force a fixed N-day catch-up window.
