Thumbnail Test Promise Alignment Visual

Inputs: [three thumbnail concepts], [video transcript], [test plan], [audience]. Check whether each thumbnail test variant makes a promise the actual video fulfills. Link visual claims to transcript evidence, distinguish curiosity from a false reveal and keep the video unchanged across the planned test. Do not invent click-through results or platform experiment capabilities. Produce a three-thumbnail contact sheet using only transcript-supported subjects with equal crop and typography areas. Adapt the presentation to [audience] and [tone]. Check the defining task detail against the inputs before finishing.

Use the attached references only for the specified visual attributes. If a required reference is missing, request it before generation. Produce one finished image with a deliberate focal point, consistent geometry and clean margins. Keep any exact wording on a separate editable label layer or leave its area blank. Do not invent evidence or present an illustration as documentary proof.
