+# ── 24-hour messaging window & notification templates ─────────────────
+# WhatsApp only allows free-form text messages within 24 hours of the last
+# inbound message from a user.  For proactive pipeline notifications sent
+# after the window expires, an approved Meta message template is used.
+#
+# Register the template in the Meta Business Manager:
+#   1. Go to Business Settings → WhatsApp → Message Templates → Create.
+#   2. Category: UTILITY
+#   3. Template name: pipeline_notification   (or your chosen name below)
+#   4. Language: English (en_US)
+#   5. Body text (example):
+#        Story *{{1}}* has moved to *{{2}}*.
+#      Where {{1}} = story name, {{2}} = pipeline stage.
+#   6. Submit for review.  Meta typically approves utility templates within
+#      minutes; transactional categories may take longer.
+#
+# Once approved, set the name below (default: "pipeline_notification"):
+# whatsapp_notification_template = "pipeline_notification"
