"""Registry of the Flutter apps that use the shared icon family.

Adding a new app here (plus a glyph in :mod:`python_pkg.app_icons.glyphs`) is
all that is needed for it to get an on-style icon. The accent is the one
shared family accent (`#B8862E`, from the `unified-design-system` skill) —
apps are distinguished by glyph shape, not color; do not give a new app its
own accent.
