/**
 * One row per calendar day, upserted by the cleanup cron
 * (lib/analytics/cleanup.ts) from raw analytics-events BEFORE those raw rows
 * age out. This is what lets aggregated history survive well beyond the raw
 * retention window (default 90 days raw vs. 12 months aggregated - see
 * globals/AnalyticsSettings.ts) without keeping individual events around.
 *
 * Not currently read by the main Analytics dashboard filters (those all
 * stay within raw retention by design - see the implementation plan); this
 * exists so long-term aggregated history isn't silently lost once raw
 * events are purged, and is available for a future longer-range view.
