/* ============================================================================
   XINNACE v3 — page-about.css
   The "about" artifact's own stylesheet, verbatim, less the 35 chrome rules
   that base.css now owns for every page, and less --maxw / --gutter / --head-h,
   which are shared so the bar and the column do not change between pages.
   Loads AFTER base.css, so everything here wins. Regenerate, do not edit.
