"""Render the home-screen icons the payload serves, with the launcher's own
drawing code, so the page's icon is the app's icon.

    python3 tools/make_icons.py

Writes client/icon-192.png, which the manifest and iOS both use. One size only:
the dithered gradient does not compress, and a 512 copy would add 150 KB to the
payload for a splash screen a plain-HTTP shortcut never shows.
Needs the launcher toolchain image (clang for the host); tests/test_launcher.py
checks the committed files still match a fresh render.
