# DELIBERATELY ABSENT: a `fun:napi_create_reference` suppression.
# Every persistent handle this addon creates is allocated through
# napi_create_reference, so suppressing that frame would hide a leaked
# Napi::Reference -- one of the most likely real defects in an addon of this
# shape. If Node's own internals prove noisy here, suppress the specific
# node:: frame, never the napi_ entry point.
