So I went outside to take a break. It seems to be wheat harvesting day, so I could take a gander at the machines trundling around, like a real grockle. ☺
Well, we ended up calling 112 after all, but for a different reason than nutty Parisiens. This full-sized video grab explains it well:

What you can see, I should point out, is a large and growing fire and that white and green thing above the '22' in the date is a farmer tearing through the field with a large plough.
Loads of kudos to the farmers! Three of them came with their ploughs and circled around, because it was a breezy day where the wind changed direction on a heartbeat. This action, and this action alone, is probably what kept the fire contained - after all, when we called the emergency services the man said it was okay, they were on the way, and it took a further ten minutes before we saw fire equipment turn up.
To be honest, I am actually surprised nobody thought to drag out the pipelines from the maïze sprayer and point that into the fire.
