Her Ignition Ability is called "Clematis" - an Ignition Ability that allows her to ignite flames on her fan. That's what an Ignition Ability is, not just "free manipulation of fire on anything of the sort". That's why we haven't seen Shinra (for example) manipulating flames from his other body parts, except his legs.

Hibana did nothing offensive with "Clematis" so it is not an attack that sterns from her Ignition Ability, so it's the ignition ability itself.

"Ignition Ability" - an ability of (Third?) Generations that allows them to ignite a body part or an object, enveloping in in flames.

That's what is said (albeit in different words) in the manga.
