# Production Apple client builds — runs on the macos-arm64 runner (home-mac-mini-1).
#
#   Tag v* (or workflow_dispatch):
#     macOS  -> Developer ID signed + notarized + stapled .dmg, attached to a Gitea
#               release on tag pushes
#     iOS    -> archive + upload straight to TestFlight (App Store Connect)
#     tvOS   -> not built: the Rust core needs tier-3 targets (nightly -Zbuild-std)
#     macOS App Store/TestFlight -> deferred: needs App Sandbox entitlements first
#               (network client + Bonjour); the Developer ID build covers macOS today.
#
# One App Store listing for all platforms (universal purchase): every target shares the
# bundle ID io.unom.punktfunk.
#
# Secrets: DEVID_CERT_P12_B64 / DEVID_CERT_PASSWORD (Developer ID Application cert),
# ASC_API_KEY_P8 / ASC_API_KEY_ID / ASC_API_ISSUER_ID (App Store Connect API key —
# notarization, TestFlight upload, and automatic-signing profile fetch).
#
# Needs a RELEASE Xcode on the runner (App Store rejects beta-SDK builds); the workflow
# picks the first non-beta /Applications/Xcode*.app and only falls back to a beta with a
# loud warning.
