# Local / OpenAI TTS API Configuration (default)
# Suggest using https://github.com/remsky/Kokoro-FastAPI
#
# NOTE: On first boot, the server auto-seeds these values into a "default-openai"
# admin-managed shared provider (DB-backed, encrypted at rest). After that, the
# admin UI is authoritative and changing these env vars has no effect. You may
# remove them once the seed has run. See Settings → Admin → Shared providers.
