I might post a PDF later (as the content becomes final), or make a printable view. In the meantime try this:

    # in your javascript console, paste this:
    [].forEach.call(document.querySelectorAll(".record, .calculation"), function(el){el.classList.add("selected")});
    [].forEach.call(document.querySelectorAll(".record, .calculation"), function(el){el.classList.add("annotate")});
    [].forEach.call(document.querySelectorAll("codesample"), function(el){el.classList.add("show")});

Then you can print the page to PDF.
