# Environment variables (CRITICAL for GPU acceleration and correct model operation)
Environment="RUST_LOG=info"

# ORT_DYLIB_PATH: Points to ONNX Runtime library (CRITICAL - without this, model produces blank output)
# Note: postinstall.js will replace __ORT_DYLIB_PATH__ with detected path, defaulting to bundled GPU library
Environment="ORT_DYLIB_PATH=__ORT_DYLIB_PATH__"

# LD_LIBRARY_PATH: CUDA runtime + ONNX Runtime CUDA providers (for GPU acceleration)
# Without this: 14x performance regression (43s vs 3-6s expected for 57s audio)
# postinstall.js dynamically detects cuDNN library paths and replaces this placeholder
Environment="LD_LIBRARY_PATH=__LD_LIBRARY_PATH__"

# CUDA_HOME: Helps CUDA libraries find additional resources at runtime
Environment="CUDA_HOME=/usr/local/cuda"

# Import full user environment for PulseAudio/PipeWire session
# This ensures all audio devices are detected properly (4 devices instead of 1)
# Required for microphone access in user session
ImportEnvironment=PATH XDG_RUNTIME_DIR

# Resource limits (commented out - let daemon use what it needs)
# Uncomment and adjust if needed for production deployments
