Thanks for doing this -- I was actually just revisiting my post as you posted, to clarify the specific things I was(n't) warning for. You are right, there are bright flashes in mine that I hadn't caught -- this is the first time I've had to think about that, and was thinking more in terms of added effects than wrt source material, and since I knew I hadn't added any as effects I didn't think of the ones in the canon.

Perhaps someone with experience wrt migraine/seizure triggers can clarify whether things like explosions or muzzle flash from gunfire counts as "bright flashing" for those purposes, since that's a common potential source?

I'm not sure I agree with you on the other points, but will consider them.
