/* OpenPress JSON Formatter & Validator interface (task 047 foundation). Loaded on the JSON Formatter Free Tool page only, after
   free-tool-single.css, inside the .op-free-tool-interface frame. Uses the theme's global tokens and the shared .op-btn, so light and
   dark follow the theme switch. The only colours this file adds are the scoped message accents below.
   Presentation only: no formatting happens here (see json-formatter.js). Reduced motion: main.css zeroes transitions globally. */
