Description

The app currently polls several endpoints (OpenSky, Oref, etc.) at fixed X-minute intervals.

• The Issue: If a user leaves the tab open for hours, they continue to hit your API thousands of times.
• The Proposal: Implement a "Tab Visibility" check in src/services/runtime.ts. If document.visibilityState === 'hidden', increase polling intervals by 5x–10x (e.g., 2m → 20m) or stop them entirely.
• Result: Significantly lower request volume for long-running sessions.
