/* E-invoice checker and viewer (einvoice_checks/*; DESIGN.md, mode Operate): the upload form, the
   verdict and the invoice laid out like a statement. Tokens, fields, panels and the FAQ come from
   site.css. The verdict, the messages and the invoice also serve the inbox in the app shell
   (shared/einvoices/*), with the shell's tokens. The verdict is a pip and a heading, never a tinted band or a thick coloured edge. */
