+ * image-crop.js — ritaglio di immagine/PDF prima dell'upload (#56).
+ *
+ * Cosa fa: ImageCrop.open(file) apre una modale con un rettangolo di ritaglio
+ *   trascinabile e ridimensionabile (mouse e touch, Pointer Events). Per un PDF
+ *   rasterizza la pagina scelta con pdf.js (>= 2000 px sul lato lungo).
+ *   Risolve: Blob PNG del ritaglio (a piena risoluzione) | il file originale
+ *   ("Usa originale") | null ("Annulla").
+ * Come si usa: ImageCrop.configure({pdfSrc, workerSrc, labels}) una volta dal
+ *   template (URL di vendor/pdf e stringhe tradotte), poi `await ImageCrop.open(file)`.
+ * Dipendenze: nessuna obbligatoria. pdf.js (gia' vendorizzato) viene caricato
+ *   al bisogno solo per i PDF; il ritaglio usa un canvas 2D semplice invece di
+ *   fabric.js perche' serve solo un rettangolo, non un editor di oggetti.
