# FieldCraft application icon

FieldCraft's mark is an L-shaped bracket with a bolt hole, drawn in isometric view and covered
by a structured hexahedral mesh with an O-grid around the hole. Its faces are separated by
transparent gaps rather than painted edge lines, so the backdrop shows through them in every
appearance. It is original artwork, attributed in `ATTRIBUTION.md`, and shares the Craft
family's layout (rounded-square backdrop, isometric floor grid, lit top faces) in its own teal.

Everything here is generated by `cargo xtask app-icon` (`xtask/src/app_icon.rs`), which computes
the geometry and draws it with VectorCraft's command-line tool (`VECTORCRAFT_CLI`, else
`vectorcraft-cli` on the PATH). Change the recipe there and rerun it; do not edit the exports by
hand. It runs on macOS (sips, iconutil, `xcrun actool`) with ImageMagick (`magick`) installed.

| File | What it is |
|---|---|
| `icon.vectorcraft`, `icon.svg`, `icon.png` | The full icon on its backdrop, 1024 × 1024 |
| `icon-small.vectorcraft`, `icon-small.svg`, `icon-small.png` | Small-size artwork used at 16–32 px: no mesh or floor grid, faces edge to edge |
| `icon.iconset/`, `icon.icns` | macOS iconset (sips) and its iconutil compilation |
| `icon.ico` | Windows icon, 16–256 px |
| `FieldCraft.icon/` | Icon Composer document: floor grid (Default and Dark), part and mesh layers, each scaled to 90% |
| `layers/*.vectorcraft` | Editable sources of the Icon Composer layers |
| `Assets.car` | `actool` compilation of `FieldCraft.icon` for macOS 26 and later (needs Xcode 26 or later; the task skips it with a note otherwise) |

The desktop app embeds `icon.iconset/icon_128x128@2x.png` as its window and Dock icon
(`apps/fieldcraft/src/main.rs`). There is no macOS bundle yet; packaging will copy
`Assets.car` and `icon.icns` into `Contents/Resources` and name `FieldCraft` in
`CFBundleIconName` / `CFBundleIconFile`.
