So a narrower tire will provide better longitudinal grip and a wider tire will provide better lateral grip.

...implies the same 195 mm tire will out-brake the 305 mm tire.
Supporting evidence would be appreciated.
BTW, I also don't see why the shape of the contact patch should relate much to lateral vs. longitudinal grip. In fact, it seems to me that the narrower tire would be better setup to transfer force to the sidewalls & wheel, in the case of lateral acceleration.
