Brand icons

The three Icon Composer projects are the source of truth for full application icons:

• dev/app-icon.icon
• nightly/app-icon.icon
• prod/app-icon.icon

Each project uses text.svg for the T3 mark and background.svg when the background is a vector layer. Additional layers use semantic names that describe their role and placement.

Run vp run icons:export from the repository root to regenerate the tracked iOS, Linux, Windows, and web assets. The development web exports are also copied to apps/web/public for the browser favicon and splash screen. Run vp run icons:check to verify that the generated assets and public copies match their sources without changing files.

Exporting requires Icon Composer 2 or newer on macOS. The script selects the newest compatible exporter from Xcode or a standalone Icon Composer installation and pins design generation 26. Set ICON_COMPOSER_TOOL to the full path of Icon Composer.app/Contents/Executables/ictool to override automatic discovery.

macOS exports

Icon Composer's command-line exporter does not expose the macOS pre-Tahoe preset. A plain command-line macOS export is full bleed and is not suitable for the desktop app, so the export script intentionally leaves the tracked macOS PNGs unchanged and prints a reminder after every run.

After changing an Icon Composer project, open it in Icon Composer and export the macOS PNG with exactly these settings:

• Platform: macOS pre-Tahoe
• Appearance: Default
• Size: 1024pt
• Scale: 1×

Save the three exports to:

• dev/app-icon.icon -> dev/blueprint-macos-1024.png
• nightly/app-icon.icon -> nightly/nightly-macos-1024.png
• prod/app-icon.icon -> prod/black-macos-1024.png

The result must be a 1024×1024 PNG with the classic macOS safe area: the opaque icon body is 824×824, inset 100 pixels on every side, with only the native Icon Composer shadow extending into the surrounding transparent canvas.

To have Codex perform the native exports, paste this prompt into a task opened at the repository root:

Use [@Computer](plugin://computer-use@openai-bundled) and the Icon Composer app to export the three macOS app icons in this repository.

For each project below, use Platform: macOS pre-Tahoe, Appearance: Default, Size: 1024pt, and Scale: 1×, then save the PNG to the exact destination:

- assets/dev/app-icon.icon -> assets/dev/blueprint-macos-1024.png
- assets/nightly/app-icon.icon -> assets/nightly/nightly-macos-1024.png
- assets/prod/app-icon.icon -> assets/prod/black-macos-1024.png

Do not resize, composite, or otherwise post-process the exported PNGs.

Verify every result is 1024×1024 and has the classic macOS safe area: an 824×824 opaque body inset 100px on every side, with only Icon Composer's native shadow extending beyond it.

Do not edit the generated PNG or ICO files directly.
