The streamlines are now banded in the fringe colours along their length, as flow speed would be, with a thin dark halo and arrowheads. Two sweep in from the lower left, climb over the cube and run straight into the top face's mesh lines, narrowing to them, so the flow becomes the structure; one wraps around the cube. The small variant keeps the cube with one bold coloured streamline and one arrow. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
FieldCraft application icon
FieldCraft's mark is a cube in isometric view, covered by a structured hexahedral mesh, whose
faces carry a banded colour fringe (blue to red, hottest at the front corner) as a stress or
temperature result would. Streamlines coloured by flow speed in the same bands, with arrowheads,
sweep in from the lower left: two run into the top face and narrow into its mesh lines, so the
flow becomes the structure, and one wraps around the cube. 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).
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.

The desktop app embeds icon.iconset/icon_128x128@2x.png as its window and Dock icon
(apps/fieldcraft/src/main.rs). The release packages (docs/releasing.md) use the rest:
packaging/macos/package.sh copies Assets.car and icon.icns (as FieldCraft.icns) into
FieldCraft.app/Contents/Resources, named by CFBundleIconName / CFBundleIconFile;
apps/fieldcraft/build.rs embeds icon.ico in fieldcraft.exe; and
packaging/linux/package.sh installs the iconset PNGs as the hicolor icons.
