Whose pick this was

Build the design, then go and look
Then go and look, in a real browser, and this is the pivot of the whole thing: every other input is a claim about the render and this is the render. Navigate, wait for the page to settle, capture, and read the computed values back rather than the class names the agent just wrote. Then keep the comparison as an assertion, because its accessibility-tree output is deterministic and can be written to a file, which is what stops the match silently un-happening in a refactor nobody connected to the design.
