# Asset attribution

Every non-code asset in this repository (fonts, icons, images, example files) 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):** MailCraft contains **no Microsoft, Google, Apple, Mozilla or other vendor's iconography, images, templates, themes, sounds, fonts or other assets**. Every asset is original work by MailCraft contributors or third-party material under an open licence (OSI open source, public domain / CC0, or a Creative Commons licence that allows redistribution). Screenshots of other vendors' software are never committed.

Generated-in-code art is original and has no file to list: the UI icon set (`crates/ui-egui/src/icons.rs`), the sample mailbox (`crates/engine/src/sample.rs`), the category colours (`crates/model/src/mailbox.rs`) and the theme colours (`crates/ui-egui/src/theme.rs`). The app icon files below are written by `cargo xtask icon` from the drawing in `assets/app-icon/source/mailcraft.svg`.
