/* =========================================================
   ToolZen Hub
   Text Diff / Compare

   Only what the shared tool styles do not already provide: the
   two input boxes, the options row, and the unified result list.
   Buttons, focus and headings come from the shared layer. Loaded
   after calculator-responsive.css.

   Added, removed, changed and unchanged lines are told by a
   symbol (+ and the minus sign), by hidden labels for a screen
   reader, by strike-through on removed words and underline on
   added words, AND by colour: never colour alone. Nothing animates.

   Narrow screens stack the boxes and wrap the result. From 900px
   the boxes sit side by side. The page itself never scrolls
   sideways: a no-wrap result scrolls inside its own box.
