In addition to the temperature difference, if an ember is shoved into something, the portion in contact is cut off from air and the burning rate slows/stops at the point of contact. Pyrotechnics like in sparklers have an oxidizer mixed in and will continue to burn even/especially with tight contact. Sparklers actually burn faster/hotter when compressed. Taping a whole bunch of sparklers tightly together becomes explosive.

Plus a lot of sparklers have a metal wire core that is efficient at transferring heat to skin. Whereas wood and charcoal are relatively insulating.

This is correct, and I appreciate the furthering of explaining why sparklers are deceptively dangerous.

People just assume its like a more familiar kind of fire and thus dramatically underestimate the danger.

Also I was going to mention the bomb thing but I decided not to, but uh yeah lol, its kind of wild that shit is legal at all, given that its pretty fucking easy to make a significantly dangerous explosive out of and, at least as far as I am aware, you basically buy all that shit with cash, unlike other types of chemicals which can be made into bombs which are pretty heavily monitored and regulated.
