Import Encoding Boundary Diagram

Create a technical diagram from [verified import pipeline] that distinguishes raw bytes, decoded text and parsed fields. Use three horizontally aligned boxes with blank editable labels and two directional arrows. Mark [documented BOM handling stage] with one accent outline. Do not imply transformations absent from the supplied implementation. Provide an accompanying label key separate from the image.

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.
