# Asset attribution

Every non-code asset in this repository (images, icons, fonts, example files, presets) is listed here with its author, source and licence. `cargo xtask assets` (part of `cargo xtask ci`) fails if an asset file is missing from this table.

**Policy (mandatory):** GridCraft contains **no Microsoft, Adobe, Avid or Autodesk iconography, images, artwork, fonts, templates, themes, table styles or sample files**. Every asset is original work by GridCraft contributors or third-party material under an open licence (OSI open source, public domain / CC0, or Creative Commons that allows redistribution). Screenshots of Microsoft software are never committed. Font files are not added here: shared fonts live in [storytold/craft-fonts](https://github.com/storytold/craft-fonts), an optional build input (`CRAFT_FONTS_DIR`). The one exception is the ArtCraft brand files in `docs/brand/`: ArtCraft trademarks, not open source, used under `docs/brand/LICENSE-brand.txt`.

Generated-in-code art is original and has no file to list: the UI icon set (`crates/ui-egui/src/icons.rs`), themes (`crates/engine/src/cmd/view.rs`), cell styles (`crates/engine/src/cmd/format.rs`), table styles (`crates/engine/src/tables.rs`), chart palettes and the sample workbooks (`crates/engine/src/sample.rs`).
