Tongue Gusset Comparison Board

Create a two-panel illustrative board from [two shoe construction references]. Show the tongue attachment area clearly in each, preserving actual seam locations and opening width. Use matching viewpoint and neutral light, with blank labels for observed features. Do not add water droplets, protection badges or unsupported performance claims. Mark unavailable internal details as unshown.

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.
