Oh wow, that's interesting. Maybe I should tape the camera all the time just in case

Alright, news on my side:
I taped the camera, did a couple of test shots and developed them in very dark darkness...
And below is a picture of the negative in the enlarger. Now even I can see the light streaks.
The question is where they come from? This is puzzling since I taped the camera. Does anybody have a good guess?
Must have happened in the camera since they are so well aligned with side holes, or am I mistaken?
Maybe I didn't tape it well? I guess I neglected the hinge area a little bit, so this might be the reason?
One silly question (film camera noob). Are the light seals usually nice and fluffy?
I'm looking at the big seal close to the hinge and it looks more like an adhesive residue in my opinion. Maybe someone removed the old ones but never put in new ones?
Edit:
The condition of the light seals
I couldn't resist making the second one black and white. It just looks much better.
The seals seem to be in a crappy condition.
