## Product visuals
TaxCorp UI and brand material from the user's project. Screenshots are of current frontend components served locally against an isolated synthetic API fixture. No production API, real client invoice, client database, or private seed data was used. All shown company names, amounts, dates, and invoice identifiers are illustrative. Queue and invoice-detail screenshots were cropped to focus the video. The opening invoice is an original HTML illustration, not a customer document. The small orange registration square is a graphic motif derived from the product's signal-orange palette.
