/* BeOS R5 "Be" Design System — standalone theme.

   Self-contained: this replaces macos-9.css entirely (it does NOT depend on it
   being loaded). It defines the full set of .mac-* chrome classes used across
   the app — windows, the signature yellow title tab, buttons, forms, tables,
   menus, modals, tabs, scrollbars — in the BeOS visual language:
     - the famous BeOS UI gray rgb(216,216,216),
     - rectangular windows with a yellow tab riding the top edge,
     - near-flat controls with thin single-pixel bevels,
     - Swiss/Helvetica type on the dusty-blue Be desktop.

   Loaded after Bootstrap so element-level rules override Reboot. The .mac-*
   class names are kept (the markup references them); only their look changes. */
