/* --------------------------------------------------------------------------
   Site-wide content link colors.
   The Evening style variation leaves links at the body-text color with no
   :visited state, so links read like plain text and never change after a
   click. Give content links a distinct blue (the same accent already used on
   the About page), a darkened-blue visited state, and a gold hover/focus that
   matches the "Featured: Black Hat USA 2013" callout (--a2-gold).
   Contrast on the #1B1B1B background:
     link    #5BA4C0  ~6.2:1  (AA)
     visited #21748C  ~3.2:1  (deliberately darkened; below AA, OK for large text)
     hover   #C9A961  ~8.0:1  (AA, gold)
   Scoped to body/content/comment areas so navigation, buttons, the site
   title, and post titles keep their existing styling. Pseudo-class selectors
   carry enough specificity to win over the theme defaults without !important.
