# ============================================================================
# tts-server (Qwen3-TTS, Vulkan) — docker compose
# ----------------------------------------------------------------------------
# Uso:
#   export RENDER_GID=$(getent group render | cut -d: -f3)   # GID gruppo render
#   docker compose up -d --build
#
# GPU: AMD/Intel via Mesa RADV (/dev/dri/renderD128). Su host dove il node
# è world-writable (es. Fedora) group_add non è necessario ma innocuo.
# NVIDIA: aggiungere il runtime nvidia (vedi README.md).
#
# Variabili utili:
#   MODELS_DIR / VOICES_DIR : percorsi di modelli e voci (default: ../../ = root del repo)
#   PORT                    : porta host (default 8881)
