# ESPAsyncWebServer includes <Hash.h> expecting the Arduino-Pico framework's Hash
# library (which provides sha1() functions). However, the Crypto-no-arduino library
# (used by dsmr) also provides a Hash.h that can shadow the framework version when
# PlatformIO's chain+ LDF mode auto-discovers it as a dependency.
# Prepend the framework Hash path to CXXFLAGS so it is found first.
