// Motivation: I didn't like the visual context switching between reading Github READMEs and npm READMEs, so I made READMEs on npm look similar to READMEs on Github.

    // I want to scale down the fonts and everything else a bit.  This was an easy way to do that.
    //GM_addStyle('.container { transform: scale(0.92); transform-origin: 50% 0; }');

    // Fill (almost) the whole width of the screen, like Wide-Github does.
    //GM_addStyle('.container { width: 98%; max-width: 100%; }');

    // Set fonts like GitHub
    GM_addStyle('#readme { font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Helvetica, Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Source Sans Pro", "Lucida Grande", sans-serif; }');

    // Set fonts how I like them (configurable through browser)
    //GM_addStyle('pre, code, kbd, samp { font-family: monospace; }');
    // I don't know why, but "monospace" shrinks the font considerably on my Linux, whilst "monospace,monospace" does not.
    // Also "monospace,monospace" is what the site itself adopted on 2018/3/22.  This rule will just ensure it stays this way!
    GM_addStyle('pre, code, kbd, samp { font-family: monospace,monospace; }');

    // Set font sizes like GitHub
    // A snippet of code appearing within a paragraph
    GM_addStyle('code { font-size: 85%; }');
    // A line of code on its own
    GM_addStyle('pre > code { font-size: 100%; }');

    GM_addStyle('.markdown .highlight, .markdown code { background-color: #f6f8fa; }');

    // More of a gap after each paragraph?  Wasn't actually needed.  The problem was wrapping due to insufficient width.
    //GM_addStyle('div, .highlight { padding-bottom: 20px; }');

    // Thicker font for section headers
    GM_addStyle('.markdown h1, .markdown h2, .markdown h3, .markdown h4, .markdown h5, .markdown h6 { font-weight: 600; }');

    // Use the npm font for section headers, even though we aren't using it for main text.  (This is a divergence from Github's markdown scheme.)
    //GM_addStyle(".markdown h1, .markdown h2, .markdown h3, .markdown h4, .markdown h5, .markdown h6 { font-family: 'Source Sans Pro', 'Lucida Grande', sans-serif; }");

    // There was absolutely no padding on the new styling.  At low widths, the text could touch the edge of the screen.  No thanks!
    //GM_addStyle(".markdown { padding-left: 1em; padding-right: 1em; }");
    // Better to do it for the whole content, including the tabs across the top
    //GM_addStyle("#top { padding-left: 1em; padding-right: 1em; }");
    // At larger widths we can enjoy greater padding
    GM_addStyle("#top { padding-left: 2%; padding-right: 2%; }");

    // Make the sidebar look like a hovering card
    // Sadly this now reaches all the way down to the bottom of the README
    GM_addStyle(".package__rightSidebar___9dMXo { padding: 0em 1.4em !important; box-shadow: 0 0 16px 0 #00000016; margin-top: 2rem; }");

    GM_addStyle(".markdown { padding-right: 0.5em; }");
    // This graph does not scale down well to low resolutions, with or without our changes.  I will wait and see if they fix that.
