          The `publish-canvas-image` workflow is now building a fresh Docker image
          (`ghcr.io/molecule-ai/canvas:latest`) in the background.

          Once it completes (~3–5 min), apply on the host machine with:
          ```bash
          cd /g/personal_programs/molecule-monorepo
          git pull origin main
          docker compose pull canvas && docker compose up -d canvas
          ```

          If you need to rebuild from local source instead (e.g. testing unreleased
          changes or a new `NEXT_PUBLIC_*` URL), use:
          ```bash
          docker compose build canvas && docker compose up -d canvas
          ```
          BODY
          printf '\n> Posted automatically by CI · commit `%s` · [build log](%s)\n' \
            "$COMMIT_SHA" "$RUN_URL" >> /tmp/deploy-reminder.md

          gh api \
            --method POST \
            "repos/${{ github.repository }}/commits/${{ github.sha }}/comments" \
            --field "body=@/tmp/deploy-reminder.md"
