# ── Keep CALL AUDIO alive when the app is BACKGROUNDED (minimised / screen locked) ──────────────────

# freezes the WebRTC mic + audio pipeline — so participants can't hear each other once the app is minimised
# or the phone locks. Declaring background audio keeps the audio session (and the app) running so a voice
# call continues in the background. (Video RENDERING still pauses while backgrounded — unavoidable in a
# WebView — but audio keeps flowing, which is what matters for a call.) Idempotent: rebuild the array each run.

# ── Push Notifications entitlement (aps-environment) ────────────────────────────────────────────────
# The @capacitor/push-notifications plugin does NOT add the Push Notifications capability to the generated
# Xcode project — in Xcode that's a manual "Signing & Capabilities → + Push Notifications" click, which
# never happens on a fresh CI checkout. Without the aps-environment entitlement, PushNotifications.register()
# fails on device ("no valid 'aps-environment' entitlement string found") and NO APNs token is ever
# obtained, so device_tokens stays empty and the server has nothing to push to. Create the entitlements
# file with aps-environment HERE; add-share-extension.rb (runs after this) MERGES the App Group into the
# same file, preserving this key. REQUIRES: the App ID com.bizgaze.connect must have the Push Notifications
# capability enabled in the Apple Developer portal, so the fetched provisioning profile carries
# aps-environment — otherwise the archive fails code-signing. "production" is correct for App Store +
# TestFlight (pair it with APNS_PRODUCTION=1 on the server).

# ── Default in-call audio to the LOUDSPEAKER (AVAudioSession) ──────────────────────────────────────
# Without this, iOS routes WebRTC call audio to the quiet EARPIECE. A Node helper (Node 20 is already set

# the speaker (headphones/Bluetooth still win when connected). The helper is tolerant and exits 0 even if
# the template differs, so it NEVER fails the build. First-pass fix — if WebRTC re-grabs the session
# mid-call on device, we follow up with a plugin that re-asserts .overrideOutputAudioPort(.speaker).
