// On ESP8266 Arduino, BearSSL is the native crypto. The mbedtls headers can
// still be in scope when a sibling component (e.g. wireguard) pulls in
// esp_mbedtls_esp8266, but that build leaves MBEDTLS_GCM_C disabled so the
// gcm.h symbols are unresolved at link time. Force BearSSL on ESP8266 to
// avoid that linker error.
