/* =========================================================
   ToolZen Hub
   JSON Formatter & Validator

   Only what the shared tool styles do not already provide: the
   two-box workspace, the status and error panel. Buttons, focus
   and headings come from the shared layer. Loaded after
   calculator-responsive.css.

   Valid, invalid and unchecked are told in words ("Valid JSON",
   "Not valid JSON"), never by colour alone. Nothing animates.

   Narrow screens stack: input, buttons, status, output.
   From 1000px the output sits beside the input and its buttons.
