Here's some photos of the relevant parts:

The brake booster and master cylinder show no signs of leakage and my brakes always feel fine even since it started leaking.

The last photo is under the car where the front is towards the right. Circled in blue is where the fluid is shown to be leaking from so the only thing I could think of that is that far towards the back of the engine bay is the clutch master cylinder.
Not sure the easiest way to get to the slave cylinder is but if it's not too hard I can try to get a photo of that as well.
