# App icon

The icon is an Icon Composer file in git: `Icon/AppIcon.icon`, a folder
with `icon.json` and SVG layers in `Assets/`. You write both by hand.
macOS adds the glass, the highlights, the shadow, the mask, and the dark,
tinted, and clear looks. You never draw those yourself.

- `tools/make_icon.sh` compiles it with `actool` into `Resources/Assets.car`
  and `Resources/AppIcon.icns`. `build.sh` runs it when the icon changed.
- `tools/icon_review.sh` renders it with `ictool` (Icon Composer's command
  line tool, inside Xcode) into one contact sheet you read.

Older app without these files: copy `Icon/`, `tools/make_icon.sh`,
`tools/icon_review.sh`, and `tools/icon_sheet.swift` from the
