+/**
+ * Lead form JS — click-to-call + SMS controls.
+ *
+ * Frappe's Phone fieldtype already renders a phone icon that routes through
+ * frappe.phone_call.handler (which we override globally), so a separate
+ * button isn't strictly required — but we add an explicit "Call / SMS" group
+ * in the menu for discoverability, mirroring the HD Ticket UX.
