An inner-system colony has restricted open-flame manufacturing after minor atmosphere drift pushed routine fabrication work into a less comfortable safety margin.
The event did not produce injury, but it did show how quickly ordinary industrial habits can become unacceptable once one environmental variable slips. Off-world manufacturing often depends less on dramatic innovation than on the quiet reliability of habitat assumptions that nobody notices until they move.
The temporary restriction is expected to remain until atmosphere discipline can be re-established across the full work cycle.
