/* FusionDrive documentation — print / PDF stylesheet
   Loaded by every docs page with media="print", and forced on screen when the page is opened with
   ?print=1 (see the inline script at the foot of each page). build_pdfs.py composes the branded PDF
   documents (cover, contents, chapters, back cover) and loads this file with media="all".

   Brand: near-black #09090B, paper white, accent pink #FF3D8A, Unbounded for display, Instrument Sans
   for text. The webfonts are embedded from /assets/docs/fonts/ so headless Chromium can render them
   without a network connection. */
