# Minimal vendored subset of the 'six' compatibility module to satisfy build-time
# test imports. This is intentionally tiny and only provides the symbols used by
# the test-suite / package (text_type, binary_type, string_types, integer_types,
# u, iteritems). It is not a full replacement for the real 'six' package.
#
# This shim avoids adding an external dependency so tests running in the build
# environment (without test-deps) can import the expected names.
