/* ==========================================================================
   Shared styles for the four page-operation tools — Merge, Split, Rotate and
   Delete. They are four pages because that is how people search: someone
   after "rotate pdf" should land on a page about rotating, not on a general
   organiser that happens to rotate. Behind the markup they are one tool, so
   the look lives here rather than four times over.

   tools/pdf-pages.js carries the behaviour; tools/pdf-engine.js the PDF work.
