/* OpenPress Image Format Converter interface (task 044 foundation; result, comparison and download styles added in 044B). Loaded on the Image Format Converter 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. Same visual language as the other tools; all selectors start with .op-ifc. Presentation only: the conversion is in
   image-format-converter-engine.js. Reduced motion: main.css zeroes transitions globally; the rule at the end repeats it for this tool. */
