Third-party material

This product bundles third-party material under its own licenses, listed below. The per-file
list (author, source, license) is in assets/ATTRIBUTION.md.

Inter (assets/fonts/Inter-*.ttf) — SIL Open Font License 1.1. See assets/fonts/OFL-Inter.txt.
Showcase photographs by Ansel Adams, Dorothea Lange and NASA (docs/images/) — public domain. See assets/ATTRIBUTION.md.

crates/segment (dac-segment) ports the SAM 3 model code of Hugging Face Transformers
(https://github.com/huggingface/transformers, src/transformers/models/sam3 and sam3_tracker),
Copyright The HuggingFace Team and Meta Platforms, Inc., licensed under the Apache License 2.0.
The port was modified by the LightCraft contributors (2026): translated from Python/PyTorch to
Rust on candle and restructured; each ported file says so. Because of this, crates/segment is
licensed under the Apache License 2.0 only (crates/segment/LICENSE-APACHE), not under MIT.
crates/fetch is likewise licensed under the Apache License 2.0 only (crates/fetch/LICENSE-APACHE).

The SAM 3 weights are not part of this software and are never distributed with it. A user downloads
the facebook/sam3 checkpoint only when they choose to (in the app, or by hand), under Meta's SAM
License (https://github.com/facebookresearch/sam3/blob/main/LICENSE), a separate, non-OSI
licence. See docs/ai-masks.md.

AI denoise weights are not part of this software and are never distributed with it.
The default build offers user-supplied models only. The optional rawnind-model
feature offers a separately downloaded RawNIND UtNet2 Bayer checkpoint under
GPL-3.0 (https://www.gnu.org/licenses/gpl-3.0.html), after the user accepts its terms.
Commercial use is subject to those terms, including applicable source, licence and
notice obligations on redistribution. Enabling that offer in releases remains a
maintainer decision. The ONNX reader and CPU/GPU executor are our Rust implementation;
no darktable, RawSpeed, LibRaw or other GPL decoder/runtime code is included.

Builds made with craft-fonts (the optional CRAFT_FONTS_DIR build input; all official releases)
also embed the fonts listed in https://github.com/storytold/craft-fonts/blob/main/ATTRIBUTION.md
(the Japanese fonts BIZ UDPGothic, BIZ UDMincho and Shippori Mincho; the web build embeds only BIZ
UDPGothic Regular), under the SIL Open Font License 1.1. Release packages include each font's
licence as OFL-<family>.txt.
