Freshness relative to snapshot

Source & definition

Weather ≤ 2 hours, modeled air ≤ 3 hours, mobility ≤ 10 minutes.

Each frame uses a retained historical snapshot with an “at or before” boundary. Weather, air, and station inventory update from stored records. Live mode queries snapshots collected by ingestion. Playback advances frames; it does not invent intermediate observations. Reduced motion disables animated map transitions.
