+ * so warn the editor at save time if the uploaded icon is too small or not
+ * square. This ENFORCES the requirement instead of silently shipping a favicon
+ * Google won't display.
+ *
+ * Attach to the favicon field's validate (or as a beforeValidate hook on the
+ * Media relationship). Non-blocking by default — returns a warning string that
+ * Payload surfaces; make it throw if you want a hard block.
+ *
+ * Note: dimensions come from the related Media doc (Payload stores width/height
+ * for image uploads), so this checks the resolved upload, not the raw file.
