Brave always returns tier 0

Brave Browse on Intel 2019 Macbook Pro (Ventura 13.2) always reports tier 0.

Chrome on the same machine correctly reports tier 3.

Hardware acceleration is enabled in Brave and confirmed to work on multiple sites.

Start by reproducing the reported comparison on the Intel 2019 MacBook Pro in Brave and Chrome, using the GPU result shown in the issue. Inspect the browser and hardware-acceleration detection path to determine why Brave reports false acceleration and tier 0; done means Brave reports the expected acceleration state and tier without regressing Chrome.
