# Regenerate every app and tray icon from the ArtCraft "A" mark in docs/brand/, rendered exactly as
# supplied. The mark is an ArtCraft trademark, NOT MIT/Apache: docs/brand/LICENSE-brand.txt.
#
# - App icon (Dock, taskbar, Start menu, Linux menus, installers): the blue mark, which is also
#   getartcraft.com's favicon.
# - Tray: the black mark as the macOS menu-bar template; the blue mark on Windows, Linux and BSD.
#
# Needs: resvg (brew install resvg / cargo install resvg). The .ico and .icns are packed by
# `cargo xtask ico` / `cargo xtask icns`, so this runs on any OS. The outputs are committed, so
# packaging (and the Rust build, which include_bytes!s some of them) never needs these tools.
