/* print-private.css: a page whose address is a customer's private key prints without the browser's header and footer
   (the owner, 29 Sep 2026: "Implement that fix"; css/report-view.css says the whole of it for the reports). A browser prints
   its own header and footer in the sheet's top and bottom margins, the page's address among them, and these pages'
   addresses carry a key: the letter preferences (/letters?t=) and the plan change (/change-plan?t=, or ?m=, the standing
   market page's own key). With no top or bottom margin nothing prints there; the 10 mm a browser's default margin held
   above and below is the body's padding instead, cloned onto every page (tests/unit/print-private-link.test.js). The site's
   header is fixed, and a fixed box prints from the top of the sheet's page area, which now starts at the sheet's edge: it
   comes down the same 10 mm, so it prints where it did. */
