/* -----------------------------------------------------------------
   Responsive overrides on top of the black_white theme.

   Theme background: the theme was written with a fixed ~900px
   desktop-era layout. Content-area children (sidebar, #content)
   have hardcoded widths, and rich content blocks (images, embeds,
   code, tables) have no max-width, so on iPad mini / phone
   viewports various bits push beyond the html max-width:70ch cap
   and cause horizontal overflow.

   These overrides do the minimum to make the site behave on
   narrow viewports without rewriting the theme.
   ----------------------------------------------------------------- */
