1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.

Short answer: Settings not marked as slot-specific will swap. Slot-specific settings (sticky) remain in their original slot. This ensures environment-specific configs like DB connections or API keys remain correct.
