/**
 * Fernwick → Spoonflower UPLOADER HEALTH CHECK (read-only, publishes nothing).
 *
 * Born 2026-07-07: the pipeline generated designs daily but published 0 for a long
 * time and NOTHING noticed — two independent silent failures (a) the stored session
 * expired, (b) Spoonflower moved the upload page to /artists/designs/new so the file
 * input was "not found". This check catches BOTH classes before a real run:
 *   - session VALID?  (logged in, not bounced to /login)
 *   - upload page REACHABLE?  (the /artists/designs/new file input is present)
 * Exits 0 = HEALTHY, 2 = DEGRADED (with a reason). Wire to a canary/cron to alert.
 *
 *   node check_health.js            # human-readable
 *   node check_health.js --json     # {healthy, session, uploadPage, reason}
