/* ==========================================================================
   QR CODE GENERATOR, BARCODES AND BATCH
   Loaded only by /qr-code-generator and its two locales, after style.css.
   Reuses .tool-box, .form-row, .form-input, .upload-btn, .tab-pill-btn and
   the .utm-finding pass, warning and fail rows. Only what is unique to this
   tool lives here. Motion uses the tokens from :root, never raw numbers.
