Deploy / deploy (push) Failing after 51s
Drives massprice.tcgplayer.com's Run Rule action per-rule on a user-configured schedule (multiple times/day, day-of-week toggles), replacing MassPrice's native scheduler (capped at 15 schedules account-wide, one run/day, with observed clock drift). Deployed via Forgejo push-to-deploy on Unraid, matching arr-summary/card-grader.
