+# EAS Workflow — production deploy for SnapBiodata (iOS)
+# Docs: https://docs.expo.dev/eas/workflows/get-started/
+#
+# Runs on EAS servers. Two ways to trigger:
+#   • automatically on every push to `main` (see `on:` below), or
+#   • manually:  npx eas-cli@latest workflow:run create-production-builds.yml
+#
+# ── One-time setup ───────────────────────────────────────────────────────────
+#   Connect this GitHub repo to the EAS project so pushes trigger the workflow:
+#   Expo dashboard → @agastyaai/snapbiodata → project settings → GitHub → connect.
+#
+# ⚠️ IMPORTANT: this submits to the App Store on every push to main. App Store
+#    review happens per submission, so for a real release cadence you likely want
+#    `submit_ios` to run only on version tags, not every push — see the commented
+#    `on:` alternative below. The `publish_update` (OTA) job is the safe
+#    every-push action for JS-only changes.
+#
+#    Android is intentionally omitted until its keystore is configured
+#    (`eas credentials` → Android). Add build_android/submit_android then.
+# ─────────────────────────────────────────────────────────────────────────────
