Proof gates — approve cheaply, render once

The storyboard already approved the words; these gates approve the rendered assets — text cards, generated images, and voice samples — before the full video render is spent. In a lecture video a wrong formula on screen is worse than no video — this is where you catch it. Click any card to approve it.
