+── ONE-TIME MANUAL STEP (needs sudo) ─────────────────────────────
+Wake the Mac nightly at 23:55 CT so the 00:00 job can fire:
+
+  sudo pmset repeat wakeorpoweron MTWRFSU 23:55:00
+
+── REQUIREMENTS for overnight runs ───────────────────────────────
+  • plugged into AC power
+  • lid OPEN (caffeinate can't beat clamshell sleep on a laptop)
+  • logged in (lock screen is fine; logged out = jobs won't run)
+  • oMLX running with a model available (it auto-starts on login)
+  • .env populated with Alpaca paper + Finnhub keys
