Repeated Query Key Parser Diagram

Create a developer teaching diagram from [confirmed parser behavior] for a URL with two occurrences of the same key. Show the two input occurrences, the parser and the resulting value representation using distinct shapes. Keep exact code labels blank for later typesetting. Do not depict first-value behavior if the supplied implementation uses a list or rejects duplicates.

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.
