This mod adds a notification system for production facilities.

Alerts are triggered in the following cases:
- Input materials drop below 5% or run out.
- Output storage exceeds 95% or becomes full (with direct selling disabled).

Each production can send only one active notification for raw materials and one for output storage to avoid spam. Priority is always given to more critical alerts.
This helps prevent production downtime or product loss.

Default keys:
- Hide/Show all notifications: Shift+Q
- Cursor Hide/Show: MMB
