/* formats.css — shared styling for the printable formats (Formats/*).
   Each format is one A4 sheet: the project's universal header (logos +
   PROJECT/AUTHORITY/... rows) on top, the test format in the middle, and the
   signature footer pinned to the bottom of the page. What you see on screen
   is what prints; fields can be typed in or left blank to fill by hand. */
