/* =========================================================
   Tech Style Ltd — tool.css

   The online JSON workbench. Loaded only by json-minifier.html,
   because nothing else on the site needs 400 lines of editor
   chrome and the other twenty pages should not pay for it.

   It inherits the site's tokens from style.css — colours, type,
   radii, edges — and adds only the pieces a two-pane editor needs.
