   brief-print.css -- the board-paper artefact.

   Q6 "a number for a board paper" ends in a print button, and a dark-themed screen page prints
   either as a flood of black ink or as unreadable grey on white. This sheet turns the brief into
   a document: ink on paper, the interactive chrome gone, nothing split across a page break, and
   the provenance kept, because a printed figure with no ladder badge is exactly the claim this
   project refuses to make.

   Loaded with media="print", so it costs a screen reader nothing.
