# Wyoming Speech-to-Text (rhasspy/wyoming-whisper).
#
# Exposes the Wyoming protocol over TCP on port 10300 so Home Assistant's
# Wyoming STT integration can stream audio and receive transcriptions. Uses
# faster-whisper under the hood with the language pinned to Catalan (`ca`).
#
# These are lightweight CPU-only pods (no GPU), so they are NOT pinned to the
# NUCBox via nodeSelector — k3s can schedule them on any amd64 node. Models are
# cached in a local-path PVC (`/data`) so they survive pod restarts without
# re-downloading.
