# `[sam]` — SAM 2 automatic mask segmentation backend.
# SAM 2 is distributed ONLY from GitHub (facebookresearch/sam2). It is intentionally NOT a
# resolvable dependency here: its setup imports torch at build time and registers under the
# name `SAM-2`, so listing it as a git ref breaks even a plain `uv sync` (which resolves all
# extras for the lockfile). It is also security-sensitive — the PyPI `sam2` package is an
# unofficial third-party upload; do not use it. Install manually from the official repo:
# git clone https://github.com/facebookresearch/sam2.git
# cd sam2 && SAM2_BUILD_CUDA=0 pip install -e . # or: uv pip install --no-build-isolation -e .
# Weights: `python scripts/download_weights.py`. This extra is a marker only; the backend
# imports sam2 lazily and degrades gracefully when absent.

# `[refine]` — DiffVG differentiable rasterizer for gradient-based refinement.

# this list. But `pydiffvg`'s own pure-Python runtime deps ARE resolvable and are pinned here so
# `uv pip install -e .[refine]` provides everything except the two vendored/built packages.
# The runtime imports pydiffvg lazily and degrades gracefully when absent.

# Corpus v1 evaluation. `svgpathtools` parses arbitrary third-party SVG into arclength-
# samplable paths, which is how ground-truth outlines are recovered from a source SVG; it also
# appears under the deprecated `[refine]` (DiffVG) extra, but the corpus must not depend on a
# deprecated optional extra to run. `fonttools` renders open-font glyphs to outline paths for
# the generated wordmark category. Both are evaluation-side only — never imported by `src/`.
