/* Mark inline code fragments in the near-universal manner pioneered by
 * Stack Overflow, then picked up by approximately everyone, including
 * us, now.
 *
 * This combinatorial selector explosion results from a need to apply
 * these stylings inside multiple page container types, multiplied by
 * the surprisingly large number of tags HTML defines for semantically
 * differentiated monospaced inline markup.  If we do not target the
 * elements we want to affect carefully, we'll end up overreaching,
 * styling Fossil UI elements that use these tags for local purposes.
 *
 * HTML generated and emitted by Fossil UI does not always fall under
 * the skin's generic rules; we must avoid intruding on its domain.
 * Our limited intent here is to style user content only, where it is
 * unreasonable to expect its author to take the time to hand-craft
 * per-document styling.  Contrast Fossil UI, which often does exactly
 * that in order to get particular results.
 *
 * Its rough equivalent in Sass syntax is far more compact, thus clearer:
 * 
 * .artifact, .dir, .doc, .forum, .wiki        // the page types we target
 *   > .content                                // hands off header & footer
 *     &, > .fossil-doc, > .markdown           // wiki, HTML & MD emb docs
 *       > p                                   // in top-level paras only
 *         > code, > kbd, > samp, > tt, > var  // monospaced tag types
 *           background-color: #f4f4f4         // pale gray box which…
 *           padding: 0 4px                    // …extends around the sides
 *
 * We then need something similar for the block-level pre elements.
 *
 * The CSS below is based on feeding that Sass code through this:
 *
 *   $ sassc code.sass | sed -e 's/, /,\n/g'
 *
 * …then hand-cleansing it to make it _somewhat_ more understandable.
 * That largely amounts to whitespace tweaks, but we've also done things
 * like trim back the forum-specific styling to apply to the default MD
 * markup only; direct HTML formatting isn't even an option there, and
 * while wiki markup _is_ supported, MD was the default from day 1.
 * Another quirk of the forum post handling is that the .markdown class
 * gets applied per-post, not up at the top level as with the wiki,
 * embedded docs, etc.

  /* Code blocks get extra indenting.  We need a selector explosion
   * equally powerful to the one above for inline <code> fragments and
   * similar elements, for essentially the same reason: Fossil UI also
   * uses <pre>, and we want to affect user content only.
   *
   * The equivalent Sass code is:
   *
   *   .artifact, .dir, .doc, .wiki       // doc types we target
   *     > .content                       // hands off header & footer
   *       @import 'pre-doc-margins.sass'
   *
   *   #fileedit-tab-preview-wrapper,     // include /fileedit previews
   *   #wikiedit-tab-preview-wrapper      // ditto /wikiedit
   *     @import 'pre-doc-margins.sass'
   * 
   * …where pre-doc-margins.sass contains the elements common to both:
   * 
   *   &, > .fossil-doc, > .markdown      // wiki, HTML & MD doc types
   *     > pre                            // direct pre descendants only
   *       margin-left: 70pt;
   *       margin-right: 50pt;
   *
   * This is a technical overreach since /wiki & /wikiedit lack support
   * for Fossil's HTML embedded doc markup capability, but we prefer to
   * draw the /fileedit parallel in our Sass example over the dubious
   * pleasure of being nit-picky on this point.  Instead, we've chosen
   * to back that overreach out by hand below.
