# A Chrome-family browser renders the UI, but none is a hard dependency: the

# Thorium, Brave) and reports clearly if none is present. The deps below are
# the ones actually linked/executed: the Dart AOT binary needs glibc,
# /usr/bin/diet-guard-app is a bash script, and the icons are installed into
# the hicolor theme hierarchy.

# !strip is LOAD-BEARING: the wrapper is a Dart AOT executable with its snapshot

# !debug because Flutter/Dart AOT release binaries carry no extractable DWARF.
