/* =========================================================
   ABBUC Forum – "Black and White" theme
   Black-and-white look of the "Kompakt" theme, but with the
   font sizes and spacing of the Standard theme (colours,
   borders and corners only – no size overrides).
   Activated by adding class "theme-bw" to <html>; forum.js
   sets/clears it and persists the choice in localStorage
   ("abbuc_forum_theme" = "bw").
