Severity & cooldown

• Severity — info, warning, error, or critical. It labels the alert and drives styling, sound-alert thresholds, and triage.
• Cooldown (minutes) — after a rule fires, it won't fire again until the cooldown elapses, even if the condition stays true. This prevents a flapping sensor from spamming you.

Choose a cooldown longer than the typical oscillation around your threshold. For a value that hovers near the limit, a 10–15 minute cooldown is usually right.
