this panel shows everything. if something looks wrong, it is wrong. that's the contract.

render both pdfs at the same scale · highlight pixel differences · runs locally

pixel-level visual diff · font hinting, anti-aliasing, and rendering-engine differences will register as changes even when the underlying content is identical · use for spot-checks, not as a certification of equivalence.
