/* ==========================================================================
   bobbykirby.com
   Hand-built. No frameworks, no build step. Edit freely.

   The idea: the site presents Bobby the way a good product listing presents
   a product. Breadcrumb, gallery, item bullets, buy box, item specifics,
   numbered catalog sections. Used with restraint so it still reads as
   credible to a hiring manager.

   Colors and fonts live in :root below; change them there and the whole
   site follows.
