/* Styles for the generated blog pages (/blog/ and /blog/<slug>/).
   Hand-written and safe to edit; the HTML in blog/ is generated, this is not.

   The tokens, typeface and label idiom are lifted verbatim from index.html so
   the blog reads as the same site. Two deliberate differences, both for
   long-form reading rather than looks:
     - the column is 560px instead of 460px (a post needs a measure);
     - the page is top-aligned instead of vertically centred (a post scrolls). */
