The maintained, font-free source is
app/webApp/src/webMain/resources/treasury.svg. It has an accessible Treasury
title and uses the same geometry and colors as the Android vector launcher icon.
With Node.js 22 or newer:
npm ci --prefix scripts
npm run icons --prefix scriptsThe lockfile pins Sharp and its standard libvips SVG renderer. No image-generation service or external assets are used. Generated assets are checked in, so ordinary Gradle/Xcode builds do not need Node or regenerate branding.
Outputs are an opaque, RGB 1024 × 1024 iOS App Store icon, a transparent desktop PNG, a Windows ICO containing 16/24/32/48/64/128/256-pixel PNG frames, and a macOS ICNS containing standard and Retina PNG representations. The ICO/ICNS containers contain only the rendered pixels and deterministic format headers. No build timestamp or random data is embedded. Re-running with the same locked tools produces identical files.
After changing the SVG, regenerate and inspect the assets, verify the iOS PNG has no alpha channel, and install platform packages to inspect launcher rendering. The Android XML paths are maintained alongside the SVG and must be updated for geometry changes. Platform launchers provide the accessible name from the app's Treasury display name.
