Configuration
morphic is configured through CLI arguments and module-level constants.
There is no configuration file.
Shared Constants
The shared module defines default thresholds and extensions used by both
the converter and dupfinder modules.

GPU Acceleration
The dupfinder module automatically detects available GPU backends in
this priority order:
CUDA (via PyTorch) — NVIDIA GPUs
CUDA (via CuPy) — NVIDIA GPUs (fallback)
ROCm (via PyTorch) — AMD GPUs
OpenCL (via PyOpenCL) — Any OpenCL-capable GPU
CPU — Multiprocessing fallback (always available)
Install optional extras to enable GPU support:
uv sync --extra cuda # NVIDIA
uv sync --extra rocm # AMD
uv sync --extra opencl # OpenCL
